Description

Hi,

SpellCheck with CustomDictionaries stopped working after an update in windows 11.

Issue also posted here https://stackoverflow.com/questions/77258504/wpf-spellcheck-on-windows-11-systems

Many thanks,

Reproduction Steps

Create WPF app. With abcd added to the Custom.lex

<TextBox SpellCheck.IsEnabled="True" Text="abcd abcd">
     <SpellCheck.CustomDictionaries>
         <sys:Uri>pack://application:,,,/Custom.lex</sys:Uri>
     </SpellCheck.CustomDictionaries>
</TextBox>

Expected behavior

abcd to not be highlighted as a spelling error

Actual behavior

abcd being incorrectly highlighted

Regression?

This worked in a previous version of windows 11.

Definitely an issue on version 23H2 22631.4037 Seems to work on an old dev machine with 22H2 22621.1265

Not sure at exactly which version this stopped working.

@Krudonix Could you update your project code? I'm afraid it's pack://application:,,,/Custom.lex's problem.

Even if I use SpellCheck.CustomDictionaries.Add(uri) to a hardcoded location it still doesn't work.
