In my testing, any of thead, th, td, tr with position:-webkit-sticky exhibit this bug. Other elements (divs, etc) draw borders correctly. 978510 1 223602 bburg 2014-02-08 20:36:11 -0800 Created attachment 223602 testcase with position:sticky thead 978519 2 223607 zalan 2014-02-08 21:34:41 -0800 Created attachment 223607 reduced test case 989996 3 hartman.wiki 2014-03-13 06:13:51 -0700 I suspect dupe of bug 94128 1292389 4 hartman.wiki 2017-03-29 08:14:32 -0700 3 years later, still a problem. https://en.wikipedia.org/wiki/List_of_Space_Shuttle_missions?withCSS=MediaWiki:Gadget-StickyTableHeaders.css The table headers here loose there borders whenever position sticky is used. 1292448 5 bburg 2017-03-29 10:04:20 -0700 *** This bug has been marked as a duplicate of bug 94128 *** 1292484 6 simon.fraser 2017-03-29 11:13:14 -0700 Does this only happen on Retina displays? 1292707 7 hartman.wiki 2017-03-29 23:18:07 -0700 @simon I just tested. No it happens on both Retina and non-Retina. Im also much less sure that this is an actual duplicate of 94128 btw. This seems much more likely to be a side effect of border collapse. 1295615 8 webkit-bug-importer 2017-04-07 19:18:02 -0700 <rdar://problem/31516367> 1452235 9 yeshar.hadi 2018-08-21 13:33:44 -0700 This issue persists on Chrome. Not sure why it's listed as resolved. I'm guessing that people have come up with workarounds over the 4+ years this has been a bug... Any suggestions would be welcomed. :) 1453020 10 hartman.wiki 2018-08-23 01:41:29 -0700 I also don't think this is the same bug as the one it was closed as a dupe of. As far as I understand, this bug occurs due to border collapsing. 223602 2014-02-08 20:36:11 -0800 2014-02-08 20:36:11 -0800 testcase with position:sticky thead testcase.html text/html 1950 bburg PGh0bWw+CjxoZWFkPgo8dGl0bGU+cG9zaXRpb246IHN0aWNreSBvbiAmbHQ7dGhlYWQ+IHdpdGgg Ym9yZGVyczwvdGl0bGU+CjwvaGVhZD4KPGJvZHk+Cgo8dGFibGUgc3R5bGU9ImJvcmRlcjogMDsg Ym9yZGVyLWNvbGxhcHNlOiBjb2xsYXBzZTsiPgo8dGhlYWQgc3R5bGU9InBvc2l0aW9uOiAtd2Vi a2l0LXN0aWNreTsgdG9wOiAwOyBmb250LXdlaWdodDogYm9sZDsgYmFja2dyb3VuZC1jb2xvcjog cmdiYSgxODAsIDE4MCwgMTgwLCAwLjgpIj4KPHRyPjx0ZCBzdHlsZT0iYm9yZGVyOiAzcHggc29s aWQgcmVkOyI+IzwvdGQ+PHRkIHN0eWxlPSJib3JkZXI6IDNweCBzb2xpZCBncmVlbjsiPkFCQzwv dGQ+PC90cj4KPC90aGVhZD4KPHRib2R5Pgo8dHI+PHRkPjE8L3RkPjx0ZD5PbmU8L3RkPjwvdHI+ Cjx0cj48dGQ+MjwvdGQ+PHRkPlR3bzwvdGQ+PC90cj4KPHRyPjx0ZD4zPC90ZD48dGQ+VGhyZWU8 L3RkPjwvdHI+Cjx0cj48dGQ+NDwvdGQ+PHRkPkZvdXI8L3RkPjwvdHI+Cjx0cj48dGQ+NTwvdGQ+ PHRkPkZpdmU8L3RkPjwvdHI+Cjx0cj48dGQ+NjwvdGQ+PHRkPlNpeDwvdGQ+PC90cj4KPHRyPjx0 ZD43PC90ZD48dGQ+U2V2ZW48L3RkPjwvdHI+Cjx0cj48dGQ+ODwvdGQ+PHRkPkVpZ2h0PC90ZD48 L3RyPgo8dHI+PHRkPjk8L3RkPjx0ZD5OaW5lPC90ZD48L3RyPgo8dHI+PHRkPjEwPC90ZD48dGQ+ VGVuPC90ZD48L3RyPgo8dHI+PHRkPjExPC90ZD48dGQ+RWxldmVuPC90ZD48L3RyPgo8dHI+PHRk PjEyPC90ZD48dGQ+VHdlbHZlPC90ZD48L3RyPgo8dHI+PHRkPjEzPC90ZD48dGQ+VGhpcnRlZW48 L3RkPjwvdHI+Cjx0cj48dGQ+MTQ8L3RkPjx0ZD5Gb3VydGVlbjwvdGQ+PC90cj4KPHRyPjx0ZD4x NTwvdGQ+PHRkPkZpZnRlZW48L3RkPjwvdHI+Cjx0cj48dGQ+MTY8L3RkPjx0ZD5TaXh0ZWVuPC90 ZD48L3RyPgo8dHI+PHRkPjE3PC90ZD48dGQ+U2V2ZW50ZWVuPC90ZD48L3RyPgo8dHI+PHRkPjE4 PC90ZD48dGQ+RWlnaHRlZW48L3RkPjwvdHI+Cjx0cj48dGQ+MTk8L3RkPjx0ZD5OaW5ldGVlbjwv dGQ+PC90cj4KPHRyPjx0ZD4yMDwvdGQ+PHRkPlR3ZW50eTwvdGQ+PC90cj4KPHRyPjx0ZD4yMTwv dGQ+PHRkPlR3ZW50eS1PbmU8L3RkPjwvdHI+Cjx0cj48dGQ+MjI8L3RkPjx0ZD5Ud2VudHktVHdv PC90ZD48L3RyPgo8dHI+PHRkPjIzPC90ZD48dGQ+VHdlbnR5LVRocmVlPC90ZD48L3RyPgo8dHI+ PHRkPjI0PC90ZD48dGQ+VHdlbnR5LUZvdXI8L3RkPjwvdHI+Cjx0cj48dGQ+MjU8L3RkPjx0ZD5U d2VudHktRml2ZTwvdGQ+PC90cj4KPHRyPjx0ZD4yNjwvdGQ+PHRkPlR3ZW50eS1TaXg8L3RkPjwv dHI+Cjx0cj48dGQ+Mjc8L3RkPjx0ZD5Ud2VudHktU2V2ZW48L3RkPjwvdHI+Cjx0cj48dGQ+Mjg8 L3RkPjx0ZD5Ud2VudHktRWlnaHQ8L3RkPjwvdHI+Cjx0cj48dGQ+Mjk8L3RkPjx0ZD5Ud2VudHkt TmluZTwvdGQ+PC90cj4KPHRyPjx0ZD4zMDwvdGQ+PHRkPlRoaXJ0eTwvdGQ+PC90cj4KPHRyPjx0 ZD4zMTwvdGQ+PHRkPlRoaXJ0eS1PbmU8L3RkPjwvdHI+Cjx0cj48dGQ+MzI8L3RkPjx0ZD5UaGly dHktVHdvPC90ZD48L3RyPgo8dHI+PHRkPjMzPC90ZD48dGQ+VGhpcnR5LVRocmVlPC90ZD48L3Ry Pgo8dHI+PHRkPjM0PC90ZD48dGQ+VGhpcnR5LUZvdXI8L3RkPjwvdHI+Cjx0cj48dGQ+MzU8L3Rk Pjx0ZD5UaGlydHktRml2ZTwvdGQ+PC90cj4KPHRyPjx0ZD4zNjwvdGQ+PHRkPlRoaXJ0eS1TaXg8 L3RkPjwvdHI+Cjx0cj48dGQ+Mzc8L3RkPjx0ZD5UaGlydHktU2V2ZW48L3RkPjwvdHI+Cjx0cj48 dGQ+Mzg8L3RkPjx0ZD5UaGlydHktRWlnaHQ8L3RkPjwvdHI+Cjx0cj48dGQ+Mzk8L3RkPjx0ZD5U aGlydHktTmluZTwvdGQ+PC90cj4KPHRyPjx0ZD40MDwvdGQ+PHRkPkZvcnR5PC90ZD48L3RyPgo8 L3Rib2R5Pgo8L3RhYmxlPgoKPGRpdiBzdHlsZT0iaGVpZ2h0OiAyMDAlOyI+PC9kaXY+Cgo8L2Jv ZHk+CjwvaHRtbD4K 223607 2014-02-08 21:34:41 -0800 2014-02-08 21:34:41 -0800 reduced test case table.html text/html 283 zalan PGh0bWw+Cjxib2R5Pgo8cD5Ub3AgYW5kIGxlZnQgYm9yZGVycyBhcmUgb3ZlcmRyYXduLjwvcD4K PHRhYmxlIHN0eWxlPSJib3JkZXItY29sbGFwc2U6IGNvbGxhcHNlOyI+Cjx0aGVhZCBzdHlsZT0i cG9zaXRpb246IC13ZWJraXQtc3RpY2t5OyB0b3A6IDA7IGJhY2tncm91bmQtY29sb3I6IGJsYWNr Ij4KPHRyPjx0ZCBzdHlsZT0iYm9yZGVyOiAxcHggc29saWQgcmVkOyB3aWR0aDogNTBweDsgaGVp Z2h0OiA1MHB4Ij48L3RkPjwvdHI+CjwvdGhlYWQ+CjwvdGFibGU+CjwvYm9keT4KPC9odG1sPg==
