Label FormattedText fails to display html text when populated via binding

[Emanuele9xx]

Description

When setting the FormattedText property of a Label control to content with simple html tags, the control display different content base on the way the FormattedText proeprty is set. When Text is set in Xaml, the label displays formatted text as expected. When Text is set via binding, the label displays text without formatting, with the html tags visible.

Expected: when using binding to populate text, the label should display html formatted content.

Steps to Reproduce

Xaml without binding (ok):

<img width="453" alt="image" src="https://github.com/dotnet/maui/assets/152969323/33c6225c-a1f2-430d-afa0-24680da02f67">

Xaml with binding (ko):

<Label
                FormattedText="{Binding MyString}"
                FontSize="21"/>

Code for binding:

Same problem for me ! solved using something like this:

FormattedText = new FormattedString
        {
            Spans = {
               new Span { Text = "Binding: ", TextColor = Colors.Red },
               new Span { Text = "\u003e", TextColor = Colors.Blue }
            }
        };

To get the correct encoding of the character I used: IconFont2Code
