I have seen this a couple of times in earlier versions, but can't reproduce it. There must be some specific condition that triggers this bug.
I have always used unmodded 64-bit drm-free Linux versions, Finnish keyboard layout, English everything else.

Probably focus is still on one of the number fields, so it's absorbing the input. We should fix it. Thanks.
