[Bug]: gibberish rgb escape codes appear in terminal

[nathanscain]

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/desktop

Steps to reproduce

1. use the terminal
2. some combination of restarts / version changes / upgrades / computer restarts (really unclear)
3. open terminal to see a bunch of escape codes typed in the terminal

Expected behavior

terminal restores to previous state without escape codes

Actual behavior

common to see escape codes in a restored terminal (the majority of my threads)

I was able to reliably reproduce this on my machine by:

1. Opening a new file in vim/nvim
2. Closing it (:q)
3. Minimise terminal with Cmd + J
4. Reopen terminal with Cmd + J
   -> Random terminal characters appended to the terminal output each time its reopened.

Typing exit in terminal to close it (instead of Cmd + J) and reopening seems to clear the issue.

No idea if this is helpful as I'm not that knowledgeable in this area, but hope it helps.

I'm experiencing same, when I switch projects or restore a terminal, the prompt gets flooded with repeated escape-reply fragments like: 2026;2$y2027;0$y2031;0$y2048;0$y1$r0m.
It seems that it happens cause replayed history contains control-query bytes, so restore keeps generating fresh replies.

@maria-rcks, could you please comment on it, does closure means that it was fixed?
