Hi Team,

I don't know whether we have this assertion or not or we have any such test failures but just wanted to raise this and get opinion whether can merge this or not:

Blink Commit - https://src.chromium.org/viewvc/blink?revision=195946&view=revision

Webkit GitHub Source - https://github.com/WebKit/WebKit/blob/492490a51a6c23ab76a9556c49c56ea445903b43/Source/WebCore/platform/graphics/opentype/OpenTypeVerticalData.cpp#L524

Just wanted to raise this bug for opinion only.

Thanks!

Test is already in WebKit and passing. Marking this as RESOLVED INVALID.
