Hi Team, Another failing test case from Blink: Test Case: https://jsfiddle.net/xpv20q5w/show 1) Click on 'green' rect on top left corner 2) See output, first value should not be 'negative', while it is in Safari Technology Preview 181 ^ Blink matched Firefox Nightly. Blink Commit: https://chromium.googlesource.com/chromium/src/+/1e8cc54d7de92498ac2f78bfccc811789a7a33b3 Just wanted to raise so we can fix it. Thanks!

Changing this function: https://searchfox.org/wubkat/source/Source/WebCore/rendering/RenderMultiColumnSet.cpp#924 >> RenderMultiColumnSet::columnTranslationForOffset Might be possible to merge but didn't explore fully.
