Issue description

Related to #7770.

After closing MenuStrip's submenu, UIA focus doesn't switch back to the top-level menu item, which may cause issues for screen readers.

Current behavior

In Narrator:

[Press Alt]
menuStrip1, Project, menu item, collapsed,
[Press Down arrow]
Project, menu,
New, menu item, Ctrl+ N,
[Press Escape]

There is no announcement that focus is now on Project menu item after pressing Escape.

In JAWS:

[Press Alt]
Menu bar
Project sub menu
[Press Down arrow]
menu
New Ctrl+N
[Press Escape]
Context Menu
Project
menu
New Ctrl+N
[Press Escape]
Context Menu
Project
menu
New Ctrl+N

After closing the dropdown, submenu is reopened and announced again as a context menu.

NVDA is similar to Narrator but focus moves to the whole window instead of staying on closed dropdown item.

Expected behavior

After dropdown is dismissed, top-level menu item is announced as currently focused item, and the focus highlight moves to it.

Steps to reproduce

1. Add a MenuStrip with a menu item with submenu (e.g. via Insert Standard Items button), or open Menus form on WinformsControlsTest app.
2. Start Narrator
3. Expand and close the menu item
