Disallow unresolved calc() in linear() timing function

lilles · chromium-wpt-export-bot · commit 86ce49f41cdc · 2025-03-31T04:16:17.000-07:00
The use of sibling-index() or sign() with element-dependent units would otherwise cause crashes. The specification says the ordering of control points should happen before computed style time, which makes the behavior undefined for element-dependent calc() expressions.
