Research direction

Start by locating the PSReadLineKeyHandler implementation for the "Copy" function and the existing AsOSC52 handling used by Set-Clipboard. Verify the behavior in WSL and confirm that Copy uses the OSC 52 path when appropriate, with tests covering the resulting clipboard behavior.

Description of the new feature/enhancement

PSReadLineKeyHandler Function "Copy" does not work when used in WSL. This might be because by default it does not use AsOSC52 method. Similar to how 'test' | Set-Clipboard wont work but 'test' | Set-Clipboard -AsOSC52 does.

Proposed technical implementation details (optional)

Allow PSReadLineKeyHandler Function "Copy" to use AsOSC52
