Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

I am working on Windows and use Acronis to connect to a MacOS machine via VNC.

When I press CMD+., it acts as Ctrl+C on the default terminal of MacOS to abort current command.

However, when using WezTerm, it only prints 6;1u on the screen.

And the leader key is set to Ctrl+A of my WezTerm config. However when I press CMD+A, it prints 7;1u.

I don't know if it's WezTerm's issue or the VNC client's issue. What does these chars mean here?
