[SamBent]

• .NET Core Version: 3.0+
• Windows version: all
• Does the bug reproduce also in WPF for .NET Framework 4.8?: Yes
• Is this bug related specifically to tooling in Visual Studio (e.g. XAML Designer, Code editing, etc...)? no

• Security issues and bugs should be reported privately, learn more via our responsible disclosure guidelines.

  Problem description:

  1. Run sample app from #4612
  2. Press TAB repeatedly to move focus to the second Image
  3. Press Ctrl+Alt+Shift+F10

  Actual behavior: The Image's ToolTip toggles on or off (perhaps after a delay due to #4615)

  Expected behavior: Nothing

Ctrl+Shift+F10 toggles the tooltip. If extra modifier keys (e.g. Alt) are pressed, no toggle should occur.

Fixed by the tooltip work in 6.0-preview7.
