Crash on space during startup

[Zoybean]

Summary

Invoking helix and then very quickly pressing space occasionally causes it to crash. I discovered this from attempting to use space p on startup. When attempting to gather data for this issue, most of the time I ran it it would succeed, but it appears to crash consistently if space is pressed ASAP after enter when invoking hx from the terminal.

Reproduction Steps

I tried this:

1. hx
2. press space after invoking hx but before helix starts

I expected this to happen:

Helix loads and has the space-menu open

Instead, this happened:

Helix crashes, sometimes briefly displaying the UI first

Helix log

No pertinent log entries even with -vvv

Platform

Windows 10

Terminal Emulator

ConEmu 160914 [64]

Helix Version

helix 22.08.1 (66276ce)

This might be Windows-only, I can't reproduce on Linux. Based on the error message it looks like it might be a bug upstream in crossterm too.

FWIW I don't seem to be able to reproduce this on Windows 10 (built from current master).

Though, I've only tried on a rather beefy machine where helix' startup is practically instantaneous.

[the-mikedavis]

This may be a problem only with ConEmu, similar to (or maybe the same as) #2490

[Zoybean]

Using the latest version of ConEmu, I can't seem to reproduce this issue. Given this was seemingly caused by the same root issue as #2490, I think it's fair to close this off as well.
