Vimium swallowing L key tap on excluded alt.org

[LyndonGingerich]

I have both https?://alt.org/nethack/hterm/* and https?://alt.org/* in my Vimium exclusions, just to be sure. When I go to alt.org/nethack/hterm, tap C to connect, and tap L to log in, the login doesn't work. It does after I disable Vimium altogether, though.

I am using Vimium 2.0.5 in Brave 1.62.165.
