Hovering over tag links removes the title attribute

While working on a userscript, I found a weird inconsistency in the markup of the front page of Super User:

enter image description here

Some tags don't get a value for their title attribute.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Is this just on Super User or on other SE sites as well? If it's only on Super User, I'd say this should be on their meta and we can migrate it there. – casperOne Jan 4 '13 at 20:49
@JollyOldSaintNicholas: Just checked the front page of Raspberry Pi. Seems to be even more wide-spread there. So, no, it doesn't seem to be an issue that's exclusive to Super User. – Oliver Salzburg Jan 4 '13 at 20:51
@JollyOldSaintNicholas Just try it on the tags to the right, no title there – Doorknob Jan 4 '13 at 20:52
Any tags you haven't moused over should still have the title. – Asad Saeeduddin Jan 4 '13 at 20:55

All tags start off with a title on them. If you have JavaScript enabled, that title gets removed in order to prevent it from showing up along with the site's generated black pop up box the moment you hover over it (even if the black pop up doesn't actually finish loading). They just never get replaced, and it really doesn't matter if they do or not because you have JavaScript enabled - you get the fancier black pop ups!

Anyways, they are there for those who do not have JavaScript enabled and need real titles.

I have fancy boxes on all tags but only some are missing the title. – Oliver Salzburg Jan 4 '13 at 20:54
@OliverSalzburg: I've tested this plenty. Viewing the source of a page as soon as it loads, every single tag has a title. The moment you hover over one, the title gets removed. So if you hover over one to right click and inspect it, it won't have a title, because you hovered over it. The tags on this question and in the right column do have titles. – animuson Jan 4 '13 at 20:55
Ah, I see now. Thanks :) – Oliver Salzburg Jan 4 '13 at 20:57
