terminal freezes when editing markdown files

[aead]

Summary

Helix seems to no longer handle keyboard events when editing markdown files after some time in alacritty and tmux.

Reproduction Steps

I tried this:

1. hx foo.md
2. Editing for a while.
3. Select multiple lines with multi-cursors by pressing C a few times.

Instead, this happened:

The hx / the tmux window does no longer accept keyboard input and they tmux window must be closed forcefully.
