Steps to reproduce

  1. Open https://twitter.com and log in.

  2. Scroll a little bit down 200-500px
    (less than a screen, I can’t reproduce it when scrolled more than a screen)

  3. Click on Reply on tweet in timeline or Tweet to on timeline of other user.
    (I wasn’t able to reproduce this when clicking on Reply in popout with recent tweet to me, probably scrolled down too much)

  4. Press Backspace or Delete button (hold for more noticeable effect)

Expected behavior: Should only result in removed text (if anything left)

Actual behavior: Text is removed and also page is scrolled up

  • I also repro, per the steps outlined above. After Pressing backspace, or delete, causes a scroll event to be fired. The page is scrolled up 1px.

    This can be confirmed by opening the F12 Developer Tools’ console, and running the following before attempting the repro:

    document.addEventListener( "scroll", event => console.log( window.scrollY ) );
    
  • Can repro. SP3 and Microsoft Edge 39.14901.1000.0

  • Doesn’t appear to reproduce on recent Windows Insider Preview builds. Please let me know if you continue to see this on recent builds. Thanks!

  • Scott L. - I cannot reproduce original issue anymore (looks like twitter redesign changed problematic behavior),
    however it is still reproducible in reduced test case provided by Jonathan S. https://jsfiddle.net/jonathansampson/2m3j5vLd/
    (Tried fiddle in other browsers but only Edge is affected)

    Microsoft Edge 41.16257.1000.0
    Microsoft EdgeHTML 16.16257

    Is it possible to update issue title so it won’t mention Twitter anymore, however underlying problem is still there

  • Interesting reduced case… I can repro there.

  • The status of this issue should be changed before it gets ignored forever.
