AnnotationInput: can we exclude space bar from keys for the auto-focus?
I know, it's getting a bit picky: I'm used to pause and play the video using the space bar when I'm annotating on the computer. I think people are used to it from YouTube or Netflix. In the post-annotator this is not possible if hitting the space bar moves the focus to the AnnotationInput field. And if I'm correct that's also not necessary. You would normally start typing with a sign or number but not with a space. Anyway, depending on how you interacted with the video controls it sometimes does not shift the focus to the input field, but works as "usually" to pause or play the video. Excluding space bar from the keys which shift the focus the input field would thus just ensure a more consistent behaviour.
Please remove the "critical" label if this is something that needs to be discussed or eats up too much time which is better invested in more critical issues.
