Issue DOES occur on Flame 2.0KK, 2.2KK

Tapping on the Facebook app menu and selecting desktop view, prevents user from pinching to zoom in and out.

I am not going to nominate this to block, as the user can still successfully navigate around the page, and the page is not zoomed too far in, or too far out to clearly see what is on the page/

Confirmed on the Flame Ref Device (2.0)
This issue was not reproducible on the Nexus 4 running Firefox Browser (FB mobile site)

@Harald, would you mind taking a quick look at the above and sharing your thoughts?  Do you think this might be a device specific issue on our end?

[:Harald Kirschner :digitarald]

I would not mark this blocking for FB but a regression in Firefox OS. FB does *nothing* to enable or disable zooming, zooming is a feature in the browser!

ni? on :kats as this might be s side effect of bug 909877.

Removing tracking Bug as blocking

I'm not ale to reproduce this on a flame running master code. I installed the Facebook app from the marketplace, started it, signed in to my Facebook account, and then selected desktop site from the bottom of the menu as shown in the video. Once the desktop version was loaded I was able to pinch-zoom just fine.

[Kartikaya Gupta (email:[e-mail])]

Given that this issue was filed a few months ago it's possible that FB was delivering a meta-viewport tag that prevented zooming to our FxOS devices at that time, and they have since changed their behaviour. I think the initial reporter here should check to see if they can still repro this.
