Slow VIM keymaps in marimo notebook

[lborcard]

Describe the bug

I think this is related to the size of my notebook but in one of my notebooks, vim keymaps are very slow. I press "I" for insert and it takes 3 seconds to enter insert mode. I don't feel anything different when operating in insert mode though. Anyone else noticed that?

I think because we update the "mode" across all editors and that may set/unset listeners and cause re-renders. We can look into optimizing.

@lborcard ~~are you still experiencing this issue? we've made some other rendering optimizations, so maybe this has gone away. i cannot reproduce it myself~~

actually the sync was regressed at some point, but i did find a fix that should help with some perf for this

thank you for the fix I indeed did not experience again. although I also try to keep my NBs shorter. thanks for the work.
