But currently we don't invalidate the style of embedded document when the color scheme of the embedder element changes. For example: <iframe style=color-scheme: dark> <iframe> <iframe> <html> If the outermost iframe changes its color-scheme, it seems WebKit doesn't pick up the change and re-evaluate prefers-color-scheme of the innermost document. 2199889 1 webkit-bug-importer 2026-04-13 14:26:53 -0700 <rdar://problem/174687101>
