ListDetailsView runtime error in Store App when spawned from VS Debug hyperlink

[XAML-Knight]

Describe the bug

When reviewing a Toolkit Docs PR, encountered a runtime error, when loading the ListDetailsView in the Store App. This error was encountered when following a hyperlink in a VS Toolkit debug session (i.e., not from within the Store App itself), which spawned the Store App with ListDetailsView as a query string value. The hyperlink in question is in the Documentation section of a sample page (You can see this in action in the Windows Community Toolkit Sample App.). The Store App was not running - clicking the hyperlink launched the Store App.

• Is this bug a regression in the toolkit? If so, what toolkit version did you last see it work:

Steps to Reproduce

• Can this be reproduced in the Sample App? (Either in a sample as-is or with new XAML pasted in the editor.)
  No - as a matter of fact, if another sample page in the Store App has already been loaded, this error is non-reproducible from within the Store App.

Steps to reproduce the behavior:

1. Run the Toolkit in Visual Studio (v16.11.3, X64/Debug)
2. Go to ListDetailsView
3. Click on 'You can see this in action'
4. See error in the Store App that has been launched

Expected behavior

Store App launches, no runtime errors occur, and user sees ListDetailsView

Screenshots

Environment

Visual Studio version 16.11.3 (X64/Debug)

Yeah, we've seen this in the past, see #3788.

It's transient and weird though, as if I hit a key in the XAML view without changing the XAML, it loads and displays. There's some other oddity going on here somehow.

We can see if just removing the styles makes it more stable?

I tried locally changing them to StaticResource (not sure why they were ThemeResource), that worked the first time. Will keep an eye on it as I test sample app for the release.

So far this switch has been working in my testing
