NVDA's focus highlighting does not correctly track objects that change their position

[k-kolev1985]

Steps to reproduce:

1. Go to NVDA menu -> Preferences -> Settings -> Vision and enable the option "Highlighting" in there. Also enable the 3 sub-options ("Highlight system focus", "Highlight navigator object" and "Highlight browse mode cursor").
2. Open a web browser and load a page in it.
3. Focus an object (e.g. a button, an edit field, etc.) in the page.
4. Scroll the page with the mouse.
5. Open a dialog of a program (the NVDA "Settings" dialog will do).
6. Focus an object in it (e.g. a button, a check box, etc.).
7. Move the window around the screen (e.g. drag it with the mouse).

Actual behavior:

NVDA's highlight rectangle stays in the position in which the focused object was before the scroll/move.

Expected behavior:

NVDA's highlight rectangle should at least try to follow the movement of the focused object, even when scrolled/moved not via the keyboard.
