You asked "Wrong how?". Title is for additional information. Alt is for textual replacement, textual substitution in case of user agent capability, internet traffic issues, wrong linkage of image, user settings. The 2 serve distinct, separate goals, purposes. Conditional content may be rendered via different mechanisms according to WAI and UAAG.

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.


> 2. Providing a @title and not providing an @alt is not a mistake per the current HTML5 draft. 

If one does not provide an alt attribute for an image, then such situation has nothing to do with this bug report.

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.

That 2011Apr/0451.html is a long document with multiple inter-linked documents and it does not address what this bug report is really about: when an alt text is provided for an img, then author-specified image placeholder dimensions should not interfere with alt text's complete rendering (as inline).
