Andreas Kling	c9cd795257	LibWeb: Don't lose change events on MediaQueryList internal state change ... MediaQueryList will now remember if a state change occurred when evaluating its match state. This memory can then be used by the document later on when it's updating all queries, to ensure that we don't forget to fire at least one change event. This also required plumbing the system visibility state to initial about:blank documents, since otherwise they would be stuck in "hidden" state indefinitely and never evaluate their media queries.	2025-02-13 20:52:31 +01:00
Andreas Kling	6fd24c2a68	LibWeb: Update layout when checking media queries inside iframes ... This ensures that the containing iframe has up-to-date viewport metrics, which is important since that may affect media query results.	2025-02-13 20:52:31 +01:00
