TextEditor horizontal scrollbar causes content to jitter/jump

[mdonatas]

Bug

What is the current behavior?
Text view content jumping around when scrollbar auto-appears

Suggestion
I'd say either have a debounce/throttle for hiding the scrollbar or once it's shown don't hide it at all. Throttling might be better.
