Bracketed paste weirdness again?

~# cat
^[[200~this is the text I want to paste^[[201~

Coincidentally, I had a lengthy conversation about nano and SSH over here: PowerShell/Win32-OpenSSH#2330
There's indeed a good chance that you're hitting this bug: https://savannah.gnu.org/bugs/index.php?66858

You can try this custom build of SSH I made if you're adventurous: PowerShell/Win32-OpenSSH#2330 (reply in thread)
It doesn't solve the issue in nano but should make it less likely to occur if it's indeed the bracketed paste bug.

No, this issue is not stale.

No, this issue is not stale.

This is not a "stale" bot.

This is a "we offered a remediation and asked you for a timely reply and didn't get one" bot.

Did you get a chance to test out either the updated build of nano or the build of sshd with a larger buffer that Leonard pointed out?

[voltagex]

Apologies.
I cannot reproduce this issue, but I am not sure what's changed - wonder if things were fixed by Windows Terminal 1.22.10731.0?
