[Bug] Printing in UWP results in crash

[ulbin]

Description of the error

When printing from WebView application crashes in Forms9Patch.UWP in file Label_Renderer.cs in routine GetDesiredSize because heightConstraint is infinite or NaN as reported by the debugger.

   public override SizeRequest GetDesiredSize(double widthConstraint, double heightConstraint)

This is not detected by the if statement, and the application crashes after successfully printing the document.

It is Failed successfully error!

Workaround

It could not be resolved using the Nuget library, but an exception can be caught using source files. The If statement in the routine should be put in try...catch, so zero is returned (return new SizeRequest(Size.Zero);) in case of the exception.

It is OK, I am using it only for printing until I am still using Xamarin.Forms. Thank you for your good work.

FWIW, I've been maintaining similar functionality for WinUI here: https://github.com/baskren/P42.Uno.HtmlExtensions/tree/main/P42.Uno.HtmlExtensions/Windows. You might find it useful.
