Exclude anchor() and anchor-size() functions from MISU

andruud · chromium-wpt-export-bot · commit 170d5c0c0c15 · 2025-08-10T08:43:04.000-07:00
These functions can become invalid at computed value time, even though they are not substitution functions. MISU [1] is not able handle this, so we just exclude those values.
