Notes from @DHowett:

In xterm, RIS disables mouse mode and (probably) resets the encoding. DECSTR does not

Environment

Windows build number: 10.0.18362.239
Windows Terminal version (if applicable): 1.5.3242.0 AND 1.4.3243.0

Debian 9.13 in WLS; RHEL7.8 on remote server

Steps to reproduce

ssh connect to the remote server do some actual work there vim, gcc, gdb, the whole daily work sh** After you’re done with work, do not disconnect the remote connections, just put your windows Laptop to “Energy saving”, remove it from the dock, put it into your bag and have a nice evening with the kids. Next day resume the Laptop, click into the one of the still open terminal panes trying to reconnect the remote machine. Try to scroll in the terminal

Expected behavior

After Wakeup from standby, I’d expect to have all the normal mouse interaction. recall the ssh login command using [Cursor up] and resume work. Vim and terminal scrolling should work.

Actual behavior

Any Mouse interaction with the terminal will spam the prompt with more or less random text (same button press creates different input in different panes) Wheel scrolling is impossible as just spams the promt. Only solution: kill all the panes, have new ones. I could live with issues like these if they would be solvable with the bash reset command. The behavior is not always reproducible. some panes work just fine. Others show even more strange behavior like flashing on mouse interaction.
