In the absence of @alt, @title is also for textual replacement. See UAAG, HTML5 etc.

> The petition, albeit not perfectly clear (683 people voted for all 3 bugs or only 1 of the 3), indicate interests and "If a bug is getting a lot of public attention, the priority may be moved up" [1]. I clearly remember voting for this bug and even said so in comment 10. Now that the voting system has been removed, the petition somehow replaces it.

@title isn't mentioned in the petition and wasn't mentioned in this bug until comment #45.

I strongly agree with modifying WebKit to display @alt text inline when @alt is present.

I'm questioning the rationale for making an *additional change* to not display @title in the same way.

I think you're mistaken. Currently WebKit shows @title inline when @alt is missing. Comment #45 is proposing changing that behavior.

> And, yes, HTML5 draft, not a PR, may allow absence of alt: when an alt text is provided, then what is HTML5 draft saying? Ian Hickson is the author behind WHATWG HTML5 and his position on how to render alt has been given by himself in comment 8. 

Ian's earlier published personal opinions to not have the weight of WHATWG and W3C. I'm not sure how many cycles he spends updating his earlier publications to match recent web standards drafts, either.

It /does/ address the change to @title proposed in Comment #45. If the patch changes behavior as proposed in Comment #45 then this discussion is indeed relevant here.
