First character ignored when starting in ssh mode

[kaddkaka]

Describe the bug

When starting wezterm-gui.exe on Windows with ssh: wezterm-gui.exe ssh user@remote_linux_machine:port and after entering the password and seeing the prompt, the first keypress is ignored. (No matter if a regular character or Enter for example)

This does not happen when starting wezterm-gui.exe and then running the ssh command inside the terminal.

Environment (please complete the following information):

• OS: Windows 10 Enterprise 1809
• Version: wezterm 20210503-220535-d64b7852
• Swedish (Sweden) and/or English (UK)

Configuration

Empty configuration file

Expected behavior

The first character should not be ignored.

@wez I have that too since you made the new ssh authent' system.
(sorry I didn't report it properly earlier, wasn't too blocking)

Yes, I confirm it's working, thank you!
