win 8.1 сенсорный .вообще нереально написать нажимая backspace чтоб стереть ошибочно написанное страницу подбрасывает вверх. и на этом точка. дальше работать соответственно не возможно. мало того в плиточном браузере вообще говорится что он не поддерживается. все браузеры у меня IE

Alternative steps to reproduce (in English, from T89196):

  1. Edit [[Nausea]] in VE:
  2. Scroll down to the "Medications" section
  3. Click in the middle of a sentence and hit "backspace" a few times.

Each time you do this, the page jumps, and the sentence in which the cursor is located always ends up at the very bottom of the viewport.

  1. Press "delete" key a few times

Same behaviour.

  1. Now click in the middle of the very long paragraph under "Diagnostic approach". Hit "backspace" a few times.

Once again, the page jumps, but now it is worse, because the page lands with the cursor offscreen.

Thanks for taking the time to report this!

Am I correct that this is about Windows 8.1 phone?
Could you provide exact steps to reproduce (step by step) in English what exactly is broken with backspace, and where exactly this happens (web address)?

Please also see because "doesn't work" isn't a good bug summary. :)

Marking as "Low" priority until more details are provided.

Testing VE (both mobile and desktop) on a tablet (not phone) with both
Windows 7 and 8.1, backspacing (both using software or hardware keyboards) works, but causes the page to abruptly scroll up. Just typing text doesn't cause this behavior. I'm going to assume that this was the original issue that was meant to be reported here :)

Added possibly-related bug 71561?

For me it scrolled abruptly almost to the top of the page (but not quite) and stayed there when I continued backspacing. I was testing on (random page), for the record.

I'd like to get a better understanding of how to troubleshoot and extend VE and this issue has been marked as very important by a client.

I've poked at similar bugs, but I'm not sure how they relate to this one and their solutions confuse me. Is there anywhere I can look for more information on tracking it down?

Probably not. We keep all existing documentation public, in source code or on

On android, 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 top paragraph, backspace to delete the dot on the end scrolls me back to | class... in the infobox.

This task is about VisualEditor. It sounds like you are talking about the mobile source editor, so please file a new task.
