Steps to reproduce

1. Use firefox
2. Enter anything in the field. It should be blocked and only show "a", but it wont on firefox.

What is expected?

It should only keep "a" and nothing else should "make it through"

What is actually happening?

Seems like either a race condition or firefox not updating at the same time as Chrome? no clue.
