   Add support for IM attribute specification over multiple segments

   Although QInputMethodEvent documents that there should be at most one
   text format attribute specified on each segment, the de-facto standard
   seems different. LyX allowed duplicate attribute specification segment
   by segment so far. This fix extends it to allow overwrapped
   specification over segments.

   Eg. existing attribute  [   seg   ] [charFormat for a segment] [seg]
       incoming attribute  [ <------ charFormat over segments ------> ]

Now I get the attached.

Interesting, I can't reproduce. Maybe a difference in versions?

$ g++ --version
g++ (Ubuntu 15-20250404-0ubuntu1) 15.0.1 20250404 (experimental) [master r15-9193-g08e803aa9be]

$ clang++ --version
Ubuntu clang version 20.1.2 (0ubuntu1)

Thanks. This seems a mistake anyway. Variable cf will not be a nullptr.

Should be fixed with commit 7d40274. As I also cannot get the error, please notify me if it is not fixed.
