Hi Team,

Thanks for looking through Blink's commit, I came across another which can be fixed:

Test Case - Look at favicon - http://mounirlamouri.github.io/sandbox/icon-test-1.html

Blink Commit - https://src.chromium.org/viewvc/blink?view=revision&revision=185957

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/platform/image-decoders/bmp/BMPImageReader.cpp#103

Just wanted to raise this bug for input and if needed then we can do 1-1 merge.

Thanks!
