Seemingly all I need to do to make it break is add a space and then a dot. " ." and it will break.

In the last example of the recording i add " f f f ." and it breaks on the "." again

I noticed the same thing, but with any number or special character after a space.

Additionally, quickly typing "asdf" repeatedly will cause the same behavior.
