possible issue in copy to clipboard from remote linux when lines end in ")"

[Marco Guardigli (mgua)]

in WT version 1.20.11271.0 i found a weird behaviour that i can not explain. It has to do with clipboard integration.

steps to reproduce:
I open a remote single window terminal against an ubuntu 22.04 system, using root account. I usually work with vertically split window. i execute remotely a command like:

nmap --dns-servers dns_server -sL 10.10.1.0/24 10.10.3.0/24 | grep -e ")$"

the output on the screen appears fine. It scrolls a few pages. No tmux or screen in between.
I then select (with mouse) the output, and copy it. Then i paste it on another windows app (notepad++)
Some of the lines have wrong line endings, with missing closing ")" and sometime a digit too.

If i execute the same command, directing the output to a file, the lines that are wrong in the paste appear normal.

To me this is quite important since i rely on being able to copy from the terminal to other apps, and need to trust the integrity of the copy.

any hints?
