Thanks! The osc52 helper indeed works fine for Alacritty -> SSH ->
screen 4.09.00.

I regularly use nested screens (local+remote), and then the helper
doesn't work anymore. I got it working again like this:

# sed -E -e 's:^:\x1bP:' -e 's:$:\x1b\\:' | \
sed -E -e 's:^:\x1bP\x1bP:' -e 's:$:\x1b\x1b\\\x1b\\\\:' | \

Not sure if there's a better way.
