847077 - Google Maps API v3 Zoom level breaks Street View Coverage Overlay

Status: RESOLVED INCOMPLETE

(Core :: DOM: Core & HTML, defect)

Description

[Andy Bajka]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:19.0) Gecko/20100101 Firefox/19.0
Build ID: 20130215130331

Steps to reproduce:

1) Created Google Map API v3 on my server
2) Zoomed CTRL-+ so that zoom level is plus one
3) Drag little man across map, at this point the Street View Coverage Overlay should turn roads with coverage blue, but does not.


Actual results:

Because I used the Zoom it breaks the Street View Coverage Overlay. Note that if I return the zoom to zero (no zoom) and reload the page, my map works fine.


Expected results:

The Zoom level in Firefox breaks Google Maps API Street coverage overlay. Test with all other browsers and this problem does not occure.

Could you provide a website displaying Google Map API v3, please.
And maybe attach a screenshot of the issue (especially if it's OS-specific)

Here's a website that has a Google Map API v3.

http://www.w3schools.com/googleAPI/default.asp

Be sure to zoom in and reload the page. You will see that dragging the little man across the map does not bring up the blue lines to show Street View coverage.

This is not an OS specific problem as it occurs on Mac and Windows versions of Firefox.

Suspected: 
84b9f209a913	Matt Brubeck — Bug 564815 - Implement window.devicePixelRatio [r=jst, sr=sicking]


Offending code is in http://maps.gstatic.com/intl/en_us/mapfiles/api-3/12/1/main.js
>function pe(){return n.devicePixelRatio||ja.deviceXDPI&&ja.deviceXDPI/96||1}

So, this is the API problem and should be TE bug.

Hi,

Tested on Mac OS 10.10 with Firefox Nightly 48.0a1 and FF 45 release and I can't reproduce it. 
Reporter please retest this with the latest Firefox versions and see if you can reproduce the issue.
