On Android, Chrome, mobile view, editing any wikimedia page, using backspace or cut for deleting text, makes the screen scroll up to almost top of page. For example, I try to edit https://en.m.wikipedia.org/wiki/Ringwoodite top paragraph, backspace to delete the dot on the end scrolls me back to | class... in the infobox.
Hello, this is not an isolated problem. Some Francophone contributors complained of similar problems. Here's what I was able to gather.
Someone encountered the problem with the device Orange-Rise, on Android 6.0 with Chrome, version : 64.0.3282.137.
Two other people encountered the problem, only one person answered me. He encountered the problem on Android 5.1.0, with Chrome 65.0.3325.109, the device is Orange Dive 30 Build/LMY47D.
I also had the same problem with a One Plus 3, with Chrome, on Android 8.0. Today, it doesn't seem to be there anymore, so I don't know if it has been corrected.
