@matmarex: This seems to be still happening on Beta cluster? Maybe it does not go the top most area of the article but towards the top still. Video:

@matmarex: Thoughts on this?

@Ryasmeen I think the issue we're seeing in that video is identical to T218650: In mobile VE, using the "Format" menu causes the page to scroll up by ~half the screen every time (iOS only?). Maybe we're also seeing T219200: [Regression wmf.23] Viewport sometimes jumps to the top abruptly on mobile VE. I'm pretty sure that this bug is actually fixed, and those are separate issues, but let's keep it open until we resolve them as well and can verify this.

So @matmarex: with these two bugs being fixed, the issue of viewport scrolling to the top of the page after adding a link seems to be fixed now. However, there is still an issue where the added link still says out of view with the keyboard sliding up. I vaguely remember there being another task about this but can't find it. Is there any? And do you think we can close this one and track this part of the issue as a separate task?

I'm not familiar with that problem, and I don't recall any relevant tasks… I would prefer if we filed a separate task for it.

I filed T221723 and noted some details there.
