From eeedd85b465ee7d44e6eeb6cc3d911c61a526add Mon Sep 17 00:00:00 2001 From: John Costa Date: Sat, 28 Feb 2026 16:06:53 -0800 Subject: [PATCH 1/3] Fix percentage min/max on flex items resolving against wrong ancestor Percentage min-width/max-width/min-height/max-height on flex items resolved against the grandparent's owner size instead of the parent container's inner size. This is because boundAxisWithinMinAndMax() received mainAxisOwnerSize (the parent's parent) rather than availableInnerMainDim (the parent's inner content area) at three call sites. The fix is gated behind a new errata flag, FlexItemPercentMinMaxAgainstOwner, so consumers using Classic or All errata (e.g. React Native) automatically preserve the old behavior. Default (Errata::None) now produces correct W3C-conformant results.
