RichEditBox loses font color when switching themes #10935
Description
Describe the bug
When changing the theme (e.g. from Dark to Light), the foreground color of a text in a RichEditBox "is lost", meaning the color switches back to the default text foreground color
Why is this important?
I am using RichEditBox as a WYSIWYG editor and users can add formatting to the text (bold, italics, background color, foreground colors etc). It can happen that users either manually change the Windows theme in the Windows settings. When this happens, the color formatting gets lost
Steps to reproduce the bug
- Download and open WinUI 3 Gallery app
- Go to RichEditBox page (winui3gallery://item/RichEditBox)
- Focus text field and paste a colored text (e.g. some colored text copied from MS Word):
- Click "Toggle Theme"
- Note that the text color has changed to either black or white (depending on the theme) and is no longer colored
