@chingucoding - I think this might be related to #294, can you take a look?

That was actually introduced with #144 . However this is an issue with the underlying RichEditBox, which is currently tracked here: microsoft/microsoft-ui-xaml#1941

To restore the color of the text upon focus, we call SetText which adds a new line. Once the behavior of the RichEditBox and TextBox changes, we probably can get rid of that code and the newly added lines shouldn't be an issue anymore.

Given that we removed that code that caused this with #524 , this issue can be closed now.
