FilePicker FileTypes filtering does not work for *.msg files on Android

[ISeeBinary]

Description

When using FilePicker on Android you are unable to select *.msg files even after passing in the correct content type as a filter.

Steps to Reproduce

1. Add a FilePicker to your application
2. Create a PickOptions object and set the FileTypes to allow only "application/vnd.ms-outlook" (content type for *.msg files)
3. Call PickMultipleAsync, passing in the PickOptions
4. Navigate to the *.msg file

You are unable to select the *.msg file as it is greyed out

Is this a regression from previous behavior?

Not sure, did not test other versions

Last version that worked well

Unknown/Other

Affected platforms

Android, I was not able test on other platforms

Affected platform versions

Android 14

Did you find any workaround?

If you remove the FileTypes filter you are able to select the *.msg file, but its contect type is incorrectly reported as "application/octet-stream".
