(core) Showing a raw data section on a popup

Summary:
Show raw data will now open a popup with
raw section instead of redirecting to raw data page.

Adding new anchor link type "a2" that is able to open
any section in a popup on a current view.

Not related:
Fixing highlightMatches function, after merging core PR.

Test Plan: Updated tests
