Escape characters surround pasted text inside ssh sessions

Steps to reproduce

Through use of ssh sessions inside Windows Terminals (tab'd), the application is now inserting ^[[200~ before some text and ^[[200~ after some text in some Windows, just ^[[200~ in others and also ^[[200~^[[200~^[[201~. There is inconsistent behaviour among the tabs (with respect to the exact escape sequence inserted) except to say that paste is now broken in all of them.

Expected Behavior

Plain text to be pasted.

Actual Behavior

Escape characters before and after (in some tabs).

A similar problem is sometimes seen in MacOS iTerm2. That application has the ability to "Reset" a window (command-R) which resolves the problem. There is no such per-tab function available with Windows Terminal. I tried running "reset" from the terminal window and a "right-click" paste after that prints the follwing in cat:

^[[200~^[[200~^[[200~^[[201~^[[201~

If I were to guess, judging by the comments in other tickets the problem lays in whatever it is that sends the "paste-block-start" not being able to send the "paste-block-end", potentially due to WiFi connection being lost, etc. If the only way to fix this is to quit all the infected terminal tabs, I'm not a particularly happy camper. "Don't do that", you say? We (users) are not always in a position to exit editors nicely.

This behavior is observed in some terminal emulators and without ssh if you paste text with ctrl-v instead of ctrl-shift-v or shift-insert

Looks like this is a /dup of #14258. At this point, this seems to be an incompatibility issue between shells. See https://askubuntu.com/a/991550.
