[Screen Reader - Windows Powershell]: In scan mode user is not able to activate dropdown as combined focus is navigating to 'New tab' split button.

[Chandresh1007]

User Experience:
If any application does not expose information and mechanisms necessary to track focus, text insertion point, and selection attributes (e.g. whether text has been selected for copy/paste) of user interface components, it would be difficult for the platforms that provide Accessibility APIs, and would in turn affect the screen reader dependent users to determine the focus

Test Environment:
OS: Win 10 2004 Build (20262.1010)
App: Windows Terminal
App version: 1.4.3243.0

Repro Steps:

1. Open Windows terminal app.
2. Launch Narrator.
3. Turn on the scan mode of the narrator using "Caps+Space".
4. Now navigate using Up/Down arrow key to New tab split button.
5. Now try to open the flyout/dropdown using keyboard "Alt down" key.
6. Observe the issue.

Actual Result:
In scan mode user is not able to activate dropdown as combined focus is navigating to 'New tab' split button.

Expected Result:
In scan mode user should be able to activate dropdown by any keyboard key defined which should be announced by the narrator.
Or, Separate focus should navigate to 'New tab' button and dropdown button.

Note: NVDA browse mode is not working.

I could have sworn we already had this bug filed on us, and it got move upstream to the WinUI repo...

A few things:

1. SplitButton's "More Options" button is not keyboard accessible microsoft-ui-xaml#1238 was filed on XAML. They're considering how to get around this.
2. I'll copy this comment since it has some good info:
   • Alt+Down opens the split options, consistent with the Office control set. With narrator, the secondary action should open the overflow.
3. We have an openNewTabDropdown action.
   • use Ctrl+Shift+Space to open the dropdown (only works when focused on shell)
   • the user can introduce their own keybinding for openNewTabDropdown to open it with their custom keybinding

@Chandresh1007 Is this sufficient to close this issue?

@carlos-zamora Pressing 'Alt+Down' to open the flyout of the split button the focus is navigating to the tab and then by pressing 'Alt+Down' once more, the flyout is getting open. Here, the flyout should get open by pressing 'Alt+Down' key once.
Also it would be good, if narrator announces the information that press 'Alt+down' to open the flyout.
