Steps to reproduce

It is very convenient to use emacs to reproduce this, since it can show received key sequences

1. All shortcuts in Terminal need to be unbound, so open settings and set every command in keybindings to null.
2. Open emacs
3. Press C-h l (for non-emacs users, Control+h then L by itself). This shows the most recent key sequences at the bottom.
4. Press C-, or C-. or C-; or C-'
5. Press C-h l again. None of the above sequences are displayed.

It is possible to bind one of those keys to an actual emacs command, just to make sure emacs isn't dropping a sequence it doesn't care about, but the result should be the same.

Note that pressing the four above punctuation keys by themselves, or combined with Shift, works as expected.

Expected behavior

C-h l should display all of the entered sequences. If a command is bound, it should execute.

Actual behavior

No sequences are displayed, no commands execute.
