Html encoded less than character "<" does not display in a Label when followed by a character immediately after

### Description

Attached is a repository with a repro case where, in a Maui application, a `Label` with the TextType being set to `Html` does not properly display Html encoded less than characters (`<` or the encoded value `<`) when followed immediately with another character (not a space). In the repro example I have linked below, I follow the encoded value with an `a`, so the text is set to `<a`. So it should display ``
3. Go to `MainPage.xaml.cs` and add the text to that label with an HTML encoded "less than" character, followed immediately with another character (not a space, i.e. `InvalidLabel1.Text = "Does not work => <a";`)

### Link to public reproduction project repository

https://github.com/Jadekyle24/LessThanHtmlNotDisplayingRepro/blob/master/LessThanHtmlNotDisplayingRepro/MainPage.xaml.cs

### Version with bug

9.0.51 SR5.1

### Is this a regression from previous behavior?

Not sure, did not test other versions

### Last version that worked well

Unknown/Other

### Affected platforms

Android

### Affected platform versions

This scenario was recreated on Android Version 14

### Did you find any workaround?

The workaround I found that appears to be working is, instead of just using `<` or `<`, using `<` (no ending semicolon) seems to work fine.

### Relevant log output

```shell

```

Start with the linked reproduction project, especially MainPage.xaml and MainPage.xaml.cs, and run it on Android 14 with the Label's Html text containing <a. Compare the Android result with Windows or iOS, then trace the existing Label HTML handling. Done means the encoded less-than character followed immediately by another character displays correctly on Android without breaking the other examples.
