IE (9, 10 and 11) compatibility: Card does not show on 2nd hover of same link; Images are not displayed
Closed, ResolvedPublic


For first issue, see

Replication instructions:
0: find machine with internet explorer (verified with IE10 on win7, IE11 on win7 and win8.1)
1: open enwiki, log in, activate hovercards
2: hover over a link and make sure card appears
3: stop hovering, see the card disappear
4: hover over same link again
EXPECTED RESULTS: card should appear again
OBSERVED RESULTS: the card appears empty, with height=0. the little triangle is still there, and the upper and lower borders of the card are shown basically merged to one horizontal line.

(repeat steps 0,1,2 from above, for a link to an article with an image):
Notice that the image appears to be broken.
this issue is only verified with IE10 on win7. it may or may not happen with IE11.

I also happens in IE11 on Win7.

The empty hovercard may or not have a full frame.

Different links to the same article behave differently and changing behaviour:

  • Hovercard with text but no image
  • Empty hovercard but with the dimensions of a full hovercard
  • Empty hovercard with 0 height

Thanks for updating this @geraki. I am looking into it right now.

I've tested 288552: Do not directly manipulate the cached object in IE9 and IE10 on Windows 7, and Chrome (50.0.2661.102) on OS X (10.11.5) and I believe that this is fixed. If you find that the issue is still present in IE11, then please reopen the task.
