Can no longer easily select text to copy and paste

Type: <b>Bug</b>

Something changed recently with the vscode terminal + claude code. I use to be able to easily select text and let go of the left click and Ctrl+C to copy, this no longer works.

Selecting text in the vscode terminal still works fine, but with claude code running, suddenly you have to either hope that the line you want auto-copies to the clip board when you select, or press Ctrl+Shift+C while holding the left mouse down and hope that it actually copies, sometimes it does not work.

1. Open claude code
2. Do some pompting
3. Try to copy text

Sometimes it lets you copy lines just by selecting without any Ctrl+C input
Othertimes it does not and it's not easy to copy paste as described above.
