[SG-35532] Accessibility: Compare page: Focus lost when selecting a revision

Administrator requested to merge contractors/SG-35532 into main

Created by: gitstart-sourcegraph

Description

After opening Popover and selecting revision to compare on the repository comparison page the focus doesn't return to the trigger button.

  • This happens for Popover which renders Input with autoFocus

Problem description

Using a keyboard, select a revision like this: compare pic Notice that focus is lost

This happens in components with PopoverContent with text field + autoFocus inside

Expected behavior

Focus should be returned to the trigger that opened the selector (the button)

Refs

Test plan

  • Navigate to this page trigger the revision popover buttons,. These buttons should regain focus after popover is closed.
  • Do same for other use cases of popover

Limitation

Unable to cleanly maintain focus on RepoContainer's Popover since useMemo gets re-rendered (Input element's autoFocus takes the focus here) when we control open state of Popover as in other use cases.
