In MSHTML, if hidden content is shown and then immediately focused, we don't force an immediate update. This means that in browse mode, the content might not yet be present, causing incorrect reporting.

Str:

  1. Open the attached test case in IE. Ensure Javascript isn't blocked.
  2. Ensure you are in browse mode.
  3. Press the button.
  • Expected: NVDA should say: "This will get focus."
  • Actual: NVDA says: "blank"

We fixed this for Gecko in 6f04af1, but never did it for MSHTML.

In [85bd3c4]:

In browse mode in Internet Explorer and other MSHTML controls, the correct content is now reported when an element appears or changes and is immediately focused.

MSHTML vbufBackend: force an instant update of the content  for onfocus events in case the focus moves to something that was newly created/changed.
Fixes #5040.
