Text is disappearing after selection

[Dolorm]

Hi!
I'm working on a project where I want user to copy result text from TextEdit. But it disappears when I try to select it. I tried it on slint examples where there's TextEdit or LineEdit and I had the same issue. I only started using slint, so is there a way to handle this?

Is that Plasma with Wayland.
Then it should be fixed with #4188
