[Bug]: Windows High Contrast themes break UI

[joebobbio]

Affected Version

Collapse 1.83.15, but probably also any version

Bug Behavior

When Windows high contrast themes are enabled (Settings > Accessibility > Contrast themes), the entire Collapse Launcher UI becomes unusable with the following message:

Microsoft.UI.Xaml.Markup.XamlParseException: The text associated with this error code could not be found.

Cannot find a Resource with the Name/Key SmokeFillColorCollapseBrush [Line: 0 Position: 0]
   at WinRT.ExceptionHelpers.<ThrowExceptionForHR>g__Throw|41_0(Int32) + 0x42
   at ABI.Microsoft.UI.Xaml.IApplicationStaticsMethods.LoadComponent(IObjectReference, Object, Uri, ComponentResourceLocation) + 0x133
   at CollapseLauncher.Pages.HomePage.<StartLoadedRoutine>d__229.MoveNext() + 0x419

This happens on Windows 11 24H2 and potentially previous Windows versions, but I haven't tested myself.

Expected Behavior

Collapse Launcher's UI should be functional with high contrast themes enabled

Steps to reproduce

1. Enable high contrast themes in Settings > Accessibility > Contrast themes (it doesn't matter what theme)
2. Open Collapse and see the broken UI

Hi there, thank you for reporting this.
Unfortunately, due to absent of mostly app specific theme for Contrast color, the app might expect to not run properly.
We don't have current ETA to make support for Contrast-enabled theme. But probably give this a note for the future.

Implemented as of 41479dc, will be deployed in the next preview release for testing. Once that happens, @joebobbio please let us know how it feels.
