Steps to replicate the issue (include links if applicable):
What happens?:
My scroll position would get forcibly scrolled away from the field to the bottom of the inspector any time I the scroll position was at the top of the inspector.
What should have happened instead?:
The scroll position at the very least shouldn't have completely scrolled away from the input.
Someone else tested on Android and didn't see this happening, so I presume it's something to do with either iOS keyboard issues or our previous attempts to mitigate said issues.
Interestingly, this only happens when the page beneath the dialog is *not* scrolled to the top, so I suspect some of our scrolling hacks for the page toolbar are kicking in in dialog mode, which might be a simple fix...
If it isn't toolbar hacks causing it, we could just reset the page scroll to 0 while full screen dialogs are open.
I couldn't reproduce this in my local environment, but it was still happening on live. The only difference I could see was the "Open in the Wikipedia App" bar I had because the app was installed. I uninstalled the app and the problem went away...
