The Bug
I have always preferred for my open chat button to be Enter in video games. In 22w19a, the chat now opens then closes right away if the keybind for Open Chat is the Enter key. It is as if I had hit Enter twice. If I hold down the Enter key, I can type my message, and then release the Enter key to send the message.

Steps to Reproduce:
Set the key bind for Open Chat, which is "t" by default, to the Enter key.

Expected Results
You can press the Enter key, start typing, then press Enter again to send your message.

Observed Results
You have to hold down the Enter key to enter and send a message, otherwise the chat closes right away.
