Hi Team,

This is potential optimization, which might be applicable in WebKit code but couldn't at the same team or not worthwhile due to code complexity.

Although I thought to raise bug to get input.

Blink Commit: https://src.chromium.org/viewvc/blink?view=revision&revision=171031

WebKit Source: https://searchfox.org/wubkat/source/Source/WebCore/platform/graphics/GlyphPage.h#78 & https://searchfox.org/wubkat/source/Source/WebCore/platform/graphics/Font.cpp#414

Just wanted to raise. CCing - Chris - who might be interested to share his input.

Thanks!
