830314 - browser should not keep the zoom factor when navigating

Status: RESOLVED DUPLICATE of bug 868047

(Core :: Graphics: Layers, defect)

Description

[Julien Wajsberg [:julienw]]

STR:
* go to http://everlong.org/mozilla/testcase-zoom/
* zoom in, then click on link

Expected:
* the target website has zoom = 1

Actual:
* the zoom factor was kept when navigating

Please note that the target website has a meta viewport and some media queries, so it is actually adapted to work on mobile browsers. In this case we should definitely reset the zoom factor. However I'm not sure when we're navigating to a website that does not have a meta viewport command.

In Firefox/Android we always reset the zoom factor, even when going back to a previous page, which might be wrong (imho we should use the zoom factor we had previously in this page, but that could be another bug).

First link goes to a mobile-adapted website, second line goes to a non-mobile-adapted website. So you can see both behaviours.

Just to note, firefox/android had this issue in 4.0 and was fixed later on.

I don't think we can fix this on the Gaia side.

We're supposed to be resetting the zoom.

Let's do this once we land layers refactoring.

FTR this is one of PPK's grief on FxOS : https://twitter.com/ppk/status/383169960945930240

Is this a dupe of bug 868047 or are they separate issues?

Julien retested with bug 868047 and this appears to be fixed.  Marking as dupe.
