Marking this as ready for review, but this still depends on #31269.

Please make sure your runtime actually points to this branch when testing this, because it isn't invisible on my end...

IDK @przepompownia cannot reproduce. Please try `make && VIMRUNTIME=$(git rev-parse --show-toplevel)/runtime build/bin/nvim --clean +"lua require('vim._extui').enable({})"`

If cmdheight > 0 the cmdline window is created with `hide = false` and should thus never have to be unhidden in the first place. But I guess the `ext.cmdheight...

I think #33546 will avoid these problems.

> [@luukvbaal](https://github.com/luukvbaal) this is probably fixed now with your recent changes? Since callbacks can only use fast events? I was never able to reproduce the loop this issue mentions but...

Are there folds in the buffer? The foldcolumn still follows Nvim's `'foldcolumn'` option so make sure it is not disabled.

Are the contents of `test.txt` relevant (does it only crash when opening that specific file)? If so, please share it.

Need more information of your environment in that case. Nvim 0.11.1 definitely works from `--clean`... Please try to provide a backtrace.

The printed escape code is a red herring, these are a terminal response not caught by Nvim because it has already terminated. We need to figure out why.
