I think this slider blinking should be fixed:

Also what do you think about showing current from value in input(maybe we should disable it in such case) instead of keeping it empty?

Resolved comments.

I do not think we should disable it because we still should be able to modify them, slider and direction are updated automatically when you change empty input.

Finally I thought that we do not need two inputs here. Now there is only one.

I'm ok with changes. But I see one failed test with rotated images, feels its not related with this pr.

OMG, this is already the third unstable test in this PR.
I tried to fix it making assumption that reason is the same like for previous...
