[Android, iOS & Catalyst] TextDecorations Property Does Not Apply at Runtime When TextType="Html" Is Set on Label

[NafeelaNazhir]

Description

When using the .NET MAUI Label control with TextType="Html" property, the TextDecorations property does not take effect when changed during runtime. This behavior is inconsistent with the Label in plain text mode where text decoration changes are applied.

Steps to Reproduce

1. Run the attached sample FormattedTextPropertiesSample 5.zip
2. Select TextType to Plain and change TextDecorations to "Underline" or "Strikethrough" using the radio buttons
3. Observe that the text decorations are applied correctly to plain text.
4. Switch TextType to "Html" using the radio button
5. Change TextDecorations to a different value .
6. Observe that text decorations do not update in the Label's HTML rendered text during runtime

Expected Behavior
The TextDecorations property of the Label control should take effect immediately when changed during runtime, regardless of whether the Label's TextType is set to Text or Html.

Actual Behavior
When the Label's TextType is set to Html, changes to the TextDecorations property made during runtime are not reflected in the rendered text.

This is probably never going to be fixed. Mixing HTML stuff with a plain label was a bad idea from the beginning. Maybe #1082 is the way forward.
