773431 - Wikipedia mobile sliding reference div unclickable

Status: VERIFIED FIXED

(Firefox for Android Graveyard :: General, defect)

Description

[Michael Comella (:mcomella) [NI reported issues only: ex-Mozilla]]

1) Open Firefox, preferably versions 14 - 15 (standard - aurora) due to Bug 773427.
2) Click the URL bar and navigate to http://en.m.wikipedia.org/wiki/Real+
3) Scroll down until the first reference (displayed as "[1]", colored in blue as a clickable link) and tap it so that the div slides into place.
4) Click the link on the expanded div.

Expected: Firefox navigates to page the reference points to.
Actual: Nothing.

Note that the "X", the close button, is also unclickable.

If your reference div contains a link and you long press the link, you will be given the long press dialog that allows you to open the link in a new tab and such. Therefore, the problem seems to extend to short taps only.

Tested on Galaxy Nexus, Android 4.0.4.

Added see also for Bug 773427 as they are both bugs with the Wikipedia mobile reference links.

Note on the link above, the "+" is not added automatically by Bugzilla – you have to add it by hand.

The page is stopping propagation of the touchstart event, so we end up never receiving it in browser.js. This ensures we get it first so we can do our handling even if the page stops it. This behaviour is consistent with Chrome - I have a simple test page at http://people.mozilla.org/~kgupta/bug/773431.html to repro/verify this.

This is a regression from bug 744518.

Marking as verified on Firefox Mobile 16 and 15
