If you repeatedly slide your mouse back and forth over the tags listed for a question (that is, toggling their hover status many times), the user box slides farther and farther to the right, stretching the question frame (as seen by the bottom border) and causing the box to go under the right-hand sidebar and eventually off the screen, causing horizontal scrollbars (ew).

Happens both main and meta. I am using Chrome 58.0.3029.110 (64-bit) on a Windows 7 computer.

  • \$\begingroup\$ I got a related but different bug today on Safari/OSX, where it does the jiggle but doesn't progressively widen the box. \$\endgroup\$ – SevenSidedDie May 19 '17 at 17:40
  • \$\begingroup\$ Wait, actually: I do get the progressive widening if I do it enough in a row. It gives me about a dozen or so jiggles before it starts pushing the usercard sideways. \$\endgroup\$ – SevenSidedDie May 19 '17 at 17:42
  • \$\begingroup\$ As a non-mod who can't edit tags, I do not get this bug. \$\endgroup\$ – GreySage May 19 '17 at 17:43

    \$\begingroup\$ @SevenSidedDie Yeah, that seems to match the behavior I’m seeing. \$\endgroup\$ – KRyan May 19 '17 at 17:45
  • \$\begingroup\$ @GreySage That makes sense, it seems to be related to the appearance/disappearance of the edit tags button. \$\endgroup\$ – KRyan May 19 '17 at 17:45
  • \$\begingroup\$ @GreySage It seems to be attached to the hover-over button for the “editing tags inline” power, which yeah, is only enabled if one has the 10k+ reputation privileges. (You're well on your way!) \$\endgroup\$ – SevenSidedDie May 19 '17 at 17:48

    \$\begingroup\$ And another funny thing: it doesn't work on my so-old-it's-not-supported-anymore Firefox. Somebody created a bug which requires you to update your browser to see! \$\endgroup\$ – rumtscho May 19 '17 at 17:58

From Meta SE, reproduced, explained, and fixed here: User card senses danger when chasing tricky "edit tags", runs for dear life.

Turns out it was a weird JavaScript/jQuery/CSS interaction bug.


This is one of the loveliest bugs I've ever had the pleasure of reproducing.

Go, little KRyan user banner! Go, be free!

Wait, he came back! ... He's showing SevenSidedDie's user info the way out! Go, little ones! You can do it!

  • \$\begingroup\$ Yeah, it really is quite fun, I like it a lot. \$\endgroup\$ – KRyan May 19 '17 at 17:39
