When I try to fix a typo using quick edit, it flashrs, then edit box jumps quite much and I see just white. When I scroll up I find it and make my writings. After saving my position in moved toward older posts — lenghtwide as much as I scrolled.
And yes, it happened here and just couple minutes ago.
Yes sadly there are a handful of bugs that are more related to ios/safari than our own codebase. Anyways, if you have anything that you can repro quite consistently, Im happy to look at it.
