Setting a Label of TextType HTML with encoded HTML causes crash.

[drasticactions]

Description

Label supports HTML via the TextType HTML

Ex.

<Label TextType="Html" x:Name="TestLabel" />

This should render text that uses HTML to be rendered as native elements. However, if your HTML string includes HTML Encoded elements (Ex.  ) it blows up on a System.Text.Xml exception:

This causes a hard crash.

Steps to Reproduce

1. Create a Label with TextType HTML
2. Set it to a string that has HTML encoded elements in it.
3. Run it.

Did you find any workaround?

Decode the text yourself before setting it to the string with a Converter... although if you're already decoding the text, using the text type is kinda useless.

Updated the above, this should only be happening on Windows, on https://cs.github.com/dotnet/maui/blob/8e32da638be53924277d24eb7b75f255916ff828/src/Core/src/Platform/Windows/TextBlockExtensions.cs#L114

And I'm closing this as it's a dupe of #11409
