Description of problem:
1. Start Bitwig 5.3.11 Flatpak under Fedora 42 Wayland Session (it's an x11 app)
2. Open a text input box (e.g. double click a level slider to type the volume in dB)
3. Try to write into a text-box
4. close the text box
5. repeat this a couple of times until ibus is crashing
6. now no text input is accepted anymore in Bitwig text-boxes, keyboard shortcuts still work though

Version-Release number of selected component:
ibus-1.5.32-1.fc42
