Description

The abbr element (used in MediaWiki since r54241 and r54242) cannot be styled in IE 6 because IE 6 does not know about it and therefore treats it like all unknown tags: It adds two void elements to the DOM, one with the tag name "abbr" and another one with the tag name "/abbr" (sic).

This can be fixed using the technique described at http://intertwingly.net/blog/2008/01/22/Best-Standards-Support#c1201006277, possibly inside a conditional comment and only for IE 6; IE >= 7 supports the abbr element natively.

Proposed fix

This should fix it. I also had to change wikibits.js because the check for ie6_bugs was broken since r65774.

Testcase

Please note that this hack works only if it is executed before any unknown elements (see testcase). Is that still the case with ResourceLoader? r72349 is unclear to me ("all JS is now loaded at the bottom" - bottom of what?).

Proposed fix

"At the bottom" apparently means "immediately before the closing </body> tag. That is too late, IE has already misparsed everything at that point.

Reported Bug 25167 about the ie6_bugs breakage.

*Bulk BZ Change: +Patch to open bugs with patches attached that are missing the keyword*

(In reply to comment #3)

"At the bottom" apparently means "immediately before the closing </body> tag.
That is too late, IE has already misparsed everything at that point.

That's right. However as of ResourceLoader 2 there is a "position" property available in the module registry. Those registered as "top" will be loaded in the <head>.

We could either turn this property in the IEFixes-module or create a seperate module for "top" things. Given the small size of the module, I think we can just swap this module to the top and add the abbr-creation fix to it.

Hm.. it's not loaded as a module, it's loaded from wikibits.js (which is loaded from the bottom)...

1.17 has passed, moving to 2.0

entlinkt@gmx-topmail.de, can you still reproduce this issue?

entlinkt@, do you still see this problem?

I would simply wontfix that bug. It is a really minor issue and only affect IE6 which is quiet a old browser. According to our compatibility chart at http://www.mediawiki.org/wiki/Compatibility#Browser IE6 is no more eligible to get everything fixed.
