This now aborts (segfault?).  At least something different.

So, for the record, before this patch with the latest emacs-30, I get the
results in failure1.txt and with your last redisplay-skip-initial-frame patch
I get failure2.txt.

I've produced these files with

make -C test eglot-tests SELECTOR=\"rust-completion\" 2>&1 | tee failure1.txt
make -C test eglot-tests SELECTOR=\"rust-completion\" 2>&1 | tee failure2.txt
