Thanks!

We need to limit code-path changes to dark mode.

[KlausLoeffelmann]

Perfect!

@Epica3055,let'smake sure, we have this modification also in main, because I missed it there.
@merriemcgaw, @LeafShi1 FYI.

@KlausLoeffelmann
Please see this pr 13834, in which I removed these two properties
internal bool BackColorSet { get; set; }
internal bool ForeColorSet { get; set; }
I think if you think pr 13834 is reasonable, then we don't have to port this modification.
