I can confirm, was able to reproduce, this also on:

iPhone SE
iOS 12.1.4
Safari

However on iPad iOS 12.1.4 Safari it works perfectly.

Apparently it is not a touch issue, but something to do with the responsive overflow setting for small screens.

Investigated and so far I got this:

• the document tab in the sidebar has no issues with touch scroll
• only the block inspector panel has the problem
• there appears to be no CSS issue easily visible

I thought initially that the new animations may have introduced a bug and pinged @kjellr about it, but on a deeper look (removed the animations) the problem is unrelated. Not sure yet what's special about this block tab that makes it not receive the scroll focus.

@ellatrix I think @jasmussen added a PR that fixed this, I can't find it anymore. I tested on device and the simulator and cannot reproduce anymore. Can you confirm please either that it's solved or that for you it is still broken? Thank you!
