Lets say, I "decorated" it, it's a feature now 🥳.

The bug was that in certain situations a richtext editor fully rerendered itself while entering text, resulting in a loss of focus. Since the rerender is caused by deep architectural decisions, I could not get rid of it, but I could change its timing, so now the rerender happens before the user focuses the editor ☺️. Not completely happy with the solution, but better than loosing focus while entering text 😂.
