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.
