Original Pull Request: https://github.com/microsoft/terminal/pull/18949

State: closed
Merged: Yes

Summary of the Pull Request

This adds support for copying to the clipboard in conhost using the OSC
52 escape sequence, extending the original implementation which was for
Windows Terminal only.

References and Relevant Issues

The Windows Terminal implementation was added in PR #5823.

Detailed Description of the Pull Request / Additional comments

Because the clipboard can't be accessed from a background thread, this
works by saving the content in a global variable, and then posting a
custom message to the main GUI thread, which takes care of the actual
copy operation.

Validation Steps Performed

I've manually confirmed that tmux copy mode is now able to copy to the
system clipboard.

PR Checklist

Closes Mouse scrolling is not working for fullscreen CLI apps (#18943)
