via a route that was not yet handled. Actually Cyprien (the
original author) had handled this case but it got removed
because I didn't know what it was for :-). This brings back

1. Introduces another highlight for link-selector rows, with the same color as
regular selection, and allowing to overlap with regular selection.
2. Don't show "secondary" cursors (those in inactive sections), to keep a single
cursor on the screen, since having multiple (which different in color) could
cause confusion.
3. An unrelated improvement (prompted by a new fixture doc) is to default the
active section to the top-left one (rather than the one with smallest rowId).
4. Another unrelated improvement (prompted by a test affected by the previous unrelated improvement) is to skip chart widgets when searching (previously search would step through those with an invisible "cursor").
Includes also tweaks for better testing on Arm-based Macs:
- Add support for TEST_CHROME_BINARY_PATH environment variable (helpful for a Mac arm64 architecture workaround)
- Remove unsetting of SELENIUM_REMOTE_URL when running headless (unlikely to affect anyone, and can be done outside the script, but interferes with the Mac workaround)

Summary:
This adds a UI panel for managing webhooks. Work started by Cyprien Pindat. You can find the UI on a document's settings page. Main changes relative to Cyprien's demo:
* Changed behavior of virtual table to be more consistent with the rest of Grist, by factoring out part of the implementation of on-demand tables.
* Cell values that would create an error can now be denied and reverted (as for the rest of Grist).
* Changes made by other users are integrated in a sane way.
* Basic undo/redo support is added using the regular undo/redo stack.
* The table list in the drop-down is now updated if schema changes.
* Added a notification from back-end when webhook status is updated so constant polling isn't needed to support multi-user operation.
* Factored out webhook specific logic from general virtual table support.
* Made a bunch of fixes to various broken behavior.
* Added tests.
The code remains somewhat unpolished, and behavior in the presence of errors is imperfect in general but may be adequate for this case.
I assume that we'll soon be lifting the restriction on the set of domains that are supported for webhooks - otherwise we'd want to provide some friendly way to discover that list of supported domains rather than just throwing an error.
I don't actually know a lot about how the front-end works - it looks like tables/columns/fields/sections can be safely added if they have string ids that won't collide with bone fide numeric ids from the back end. Sneaky.
Contains a migration, so needs an extra reviewer for that.

such replies nicely).
Currently tested primarily through the runCompletion script,

- When selecting columns to import into a Ref column, now a Numeric column like
'Order' will produce two options: "Order" and "Order (as row ID)".
- Fixes exports to correct the formatting of visible columns. This addresses multiple bugs:
1. Formatting wasn't used, e.g. a Ref showing a custom-formatted date was still presented as YYYY-MM-DD in CSVs.
2. Ref showing a Numeric column was formatted as if a row ID (e.g. `Table1[1.5]`), which is very wrong.
- If importing into a table that doesn't have a primary view, don't switch page after import.
Refactorings:
- Generalize GenImporterView to be usable in more cases; removed near-duplicated logic from node side
- Some other refactoring in importing code.
- Fix field/column option selection in ValueParser
- Add NUM() helper to turn integer-valued floats into ints, useful for "as row ID" lookups.

like 'T.lookupOne(B' (to autocomplete columns of table T that start with "B").
Unfortunately, that interferes with common cases like 'SUM($B', since instead
of sending '$B', it is now including the function name.
To properly fix the common case, we need to exclude the function name from the
call, but for lookups we need to include it. ACE's methods aren't flexible
enough to override this logic cleanly, so some monkey-patching was needed.

This addresses two issues, differently:
- For a formula with leading whitespace, like " 1+1", it is stored as is, but
is fixed to work (it should be valid Python, and whitespace is only stripped out
at parsing time to avoid intentation errors caused by the way it gets parsed)
- For a formula with a leading equals-sign ("="), it is stripped out on the
client side before the formula is stored. Grist documentation uses leading
"=" to indicate formulas (because UI shows an "=" icon), and Excel formulas
actually contain the leading "=", so it is a common mistake to include it.

Summary:
The previous implementation for collapsing sections involved disposing of a view instance (Grid or Chart component). This caused numerous bugs with
linking sections as the implementation is located in the BaseView.js. Now the view instance is kept and attached to a dom in a hidden div, so it can respond
and function as a normal rendered section. It is also passed from between collapsed and main layout, when sections are dragged or moved using section's
menu commands (`collapse` and `add to main page`)
It also implies that the ViewLayout must still be rendered when a section is maximized (as it is responsible for the view instance), so the dom, and
some logic for rendering it, had to be changed.
