Please also add this to the _Authentication menu items and the _Experimental menu items.

Added IsCheckable="True" to all four Authentication menu items that have IsChecked bindings. The Experimental menu items already had IsCheckable="true" so no changes were needed there. The fix ensures screen readers can properly announce the selection state of these checkable menu options. Commit: 14d25d5

This PR fixes an accessibility issue where screen readers like NVDA cannot announce the currently selected theme in the Options > Theme menu.
Problem
Screen reader users were unable to determine which theme is currently selected when navigating through the Theme submenu. The selected item (Light, Dark, or System) was not being announced by NVDA, making it difficult for users to confirm their current selection or make informed changes.
Root Cause
The theme MenuItems in
MainWindow.xamlwere using theIsCheckedbinding property to display the selection state visually, but were missing theIsCheckable="True"attribute. Without this attribute, WPF doesn't properly expose the checked state to UI Automation APIs, preventing screen readers from accessing the selection information.Solution
Added
IsCheckable="True"to all three theme MenuItems:Technical Details
The
IsCheckable="True"attribute enables WPF to:This change follows the same pattern already used by other checkable menu options in the same file (lines 122, 127).
Impact
The fix is minimal and surgical, affecting only the three theme MenuItems without changing any underlying functionality.
Fixes #2236.
