The New Contributor dialog is masked from where the comment section ends.
Here are some screenshots just to be more clear:

With no comments:

    Fwiw, When I hit edit to add the "new-contributor-indicator" tag to the question, that dialog was also cut off. Aug 30, 2019 at 6:19
  • Maybe it is meant this way so we leave more "friendly" comments so we all get to see the whole dialog?

  • @rene Lol. What could that comment be then?

  • Back in the days I would be slinging insults at them but under the new Code of Conduct that has become tricky business ... ;)

  • @rene Or close the question - that works too ;) The dialog shows up correctly above the "on hold" notice. Aug 30, 2019 at 8:43
  • @InquisitiveLurker Looks like you misunderstood the bug. The dialog masks below the comment section - where the comments end

  • @BlackThunder Apologies if I was not clear - my comment was meant to imply "don't try reproducing the bug in closed questions; it seems to be only the space below the comment section that does it". It's most likely a z-index issue, so that wasn't a guarantee. Aug 30, 2019 at 8:51
  • Correction: it's not z-index, it looks like the dialog can't extend outside the <div class="post-layout"> that contains the question, on-hold notice and comments. That's about all I can tell with my mediocre "Inspect element" skills. Aug 30, 2019 at 9:06

    Reproduced on Stack Overflow and Vi.SE as well. Pretty sure it's network-wide. The bug can be forcibly reproduced by deleting the div containing the comments from the developer tools in a browser. Sep 1, 2019 at 10:50
  • @Olivia I tested it everywhere. This is why I posted here on M.SE

Fixed by Aaron: Question's first two line and the upvote arrow are clamped

The root cause here was a different change made to temporarily prevent scrolling at small screen sizes. The root cause of the scrolling was the new Share pop-up. With that identified (albeit not yet fixed), the temporary fix can be removed (and a small pile of related bugs completed).
