Typing is invisible after hitting ENTER to launch shell in current directory, if rover is bound to a shortcut in bash

[IceAsteroid]

Say that I've set the following line in .bashrc

bind -x '"\eF":"rover"'

Now I can invoke rover by hitting Alt+Shift+f.

But when I hit ENTER key to open a subshell of the directory that I'm in rover. the typing has become invisible, but it works when I hit ENTER to commit the typing.

Here's the demo
