1128034 - Flame: browser app occasionally renders webpage in fully zoomed in state when loading for first time

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Browser, defect)

Description

Attachment: test_browser_navigation_flame_0.png

When test_browser_navigation.py (https://github.com/mozilla-b2g/gaia/blob/master/tests/python/gaia-ui-tests/gaiatest/tests/functional/browser/test_browser_navigation.py)is run, the initial page is rendered in fully zoomed in state (frequency: 3 out of 5) and remains that way until another URL is entered.  I am not sure whether it is a browser issue or marionette issue.

No changes to Marionette have landed in the last few days

To be exact, the initial page displays fine, but when it goes to the community page it displays with fully zoomed-in view.  I'm suspecting this is a browser issue, but it happens intermittently so I am not sure.  I believe this was going on for a while- i just noticed it while going through the screen captures.  

Is there an easy way to manually replicate the steps with the same html files?

Okay, with the marionette webserver open, I can replicate this manually, changing component

STR:
(Option 1)
Setup python marionette, and run https://github.com/mozilla-b2g/gaia/blob/master/tests/python/gaia-ui-tests/gaiatest/tests/functional/browser/test_browser_navigation.py on flame.  out 3 out of 5 times, fully zoomed in view of the text website will appear

(Option 2)
Copy https://github.com/mozilla-b2g/gaia/blob/master/tests/python/gaia-ui-tests/gaiatest/resources/mozilla.html into a webserver, and access the webpage on flame device.  repeat 5 time or so

Actual:
The website appears fully zoomed in (see attached screenshot)
Expected:
The website displays normally

Frequency: 2 ~ 3 out of 5

Just realized that it happens on loading any text-only website like the ones mentioned Comment 4.

I can also see this happening in Firefox for Android.
Related bug 791187?

Aaron, do you know if Fennec has bugs about this lying around?

If this is a recent regression, can we get a regression window? There have been a few changes that landed recently that might be responsible but they're all only sort-of related so it would be easier to get a window and figure out what caused it.

Unfortunately this bug has been around quite a while, but I think this was considered as a low priority bug or maybe its title hasn't been worded properly.
