1219425 - "Let It Snow" Microsoft Edge demo acquires the incorrect window height of 32px

Status: NEW

(Core :: Graphics: Canvas2D, defect)

Description

[Trammel May]

Attachment: ZitoResIssue.PNG

Actual Result:
When the user attempts to watch the "Let It Snow" demo on the testdrive website for microsoft developers, the page auto-detects the wrong window size of 1047x32 and sets the image equal to that size. 

Expected Result:
The correct window size should be detected so that images and animations are displayed properly. 

Steps to Recreate:
1. Launch Firefox Developer v43 
2. Navigate to dev.modern.ie/testdrive/demos/letitsnow/
3. Observe the animated image is extremely narrow, 32 pixels to be exact, instead of the correct height adjusted to the window dimensions.

As far as I can tell we have not regressed behaviour as this reproduces back to Firefox 24 (unless we regressed it way earlier). That said, this demo works fine in Chrome and Safari.

Does not work fine in Chrome for me on OS X 10.9 - it matches what Firefox does, by starting at full width, then resizing down to 32px height.

Same build for me on Mac OS 10.11.1 shows full window height. Not sure what could be different. Perhaps try on a new Chrome profile? or perhaps it's differing hardware or OS version? I don't know.

I think it'd help to get someone on this bug from Microsoft.
