This is reproducible only when double tapping on a webpage header or its footer. If double tap gesture is made on any other part of the webpage, the zooming action is done corectly.

Reproducible: Always

Steps to Reproduce:
1. Open Fennec App
2. Browse to www.mozilla.com (desktop view)
3. Perform a double tap on the page footer
Actual Results:  
App doesn't zoom in/out on the focused point where double tap was done.

Expected Results:  
App should zoom in/out on any part of a webpage.

Are you able to reproduce this on other sites with footers or is it only a mozilla.com issue? What about multi-touch zooming? What about changing your user agent to Desktop Firefox?

Is reproducible on other sites to. I'll set the bug to new.
Ever confirmed: true
Double-tap zooms to the width of the tapped element.  If an element has the same width of the document, then double-tapping it will zoom to show the entire document width.  (This changed a bit in bug 621683.)

We might re-add a different behavior for elements that are as wide as the entire document.  We'd need to use this behavior only when reflow is disabled.

Steps to reproduce:
1. Go to http://support.mozilla.com/en-US/mobile 
2. Double tap on the Mozilla logo
3. Double tap on the website title
4. Go to https://addons.mozilla.org/en-US/mobile/
5. Repeat steps 2&3

Actual result:
After steps 2&3, the app zooms in/out the image element and the title as well.
After step 5, nothing happens.

- Please see the following video: http://www.youtube.com/user/qaioana#p/a/u/1/jpzX1mnc5yc
- If I double tap on any other elements on the page, nothing happens or the webpage just scrolls down.

For the latest Beta build (FF 10 Beta 4), the zooming works randomly: sometimes it zooms in just a little bit, not only on header/footer, but even on other text/graphic elements from the page body.

This issue was reproducible on www.mozilla.org (desktop version).
