Summary:
After an import from inside a document, one minute later, an important
QuerySet would get disposed, leaving the view section in a bad state,
and manifesting as JS errors on subsequent operations. (Might not
*always* happen because switching pages would prevent it from
manifesting, I think.)
Bad state that I've seen after transforms is probably explainable as
this bug, which is unrelated. Reproduction was hard because who knew one
had to wait a minute?!
Test Plan:
Added a unittest for the fix in QuerySet, and a browser test that
fails without the fix (JS errors, bad state), and passes with.
