Calc iOS: scrolling horizontally causes vertical jump #9679

When scrolling horizontally in calc, you can sometimes trigger a jump.

Steps:

Open a calc file in a small screen mobile device
Click to edit mode. Click into a cell.
Scroll the file across the Columns (Swipe fingers a few times forward and a few times backwards)

Notice that you occasionally jump through rows, sometimes over a thousand rows at a time

Expected: The row should remain while only the columns scrolls, or should change very little (i.e. if you didn't swipe exactly horizontally). The amount of scrolling we see here is intermittent and abnormal

I think this happens on Android and iOS - but it seems much more possible and severe to reproduce on iOS - although that could be a screen size thing(?)

i.e. if you didn't swipe exactly horizontally

This should probably also be changed, but is out-of-scope for this issue...

Can we have a video for this issue?

hi @eszkadev - sorry, I've found this really hard to reproduce, and I don't have a video that I can share publicly -- direct message me and the answer will be different
