LibWeb: Don't crash when accessing property in detached Window object After removing an iframe from the DOM, its contentWindow will be detached from its browsing context, per spec. Because the contentWindow is still accessible, we cannot assume that Window objects always have an associated browsing context. This needs to be fixed in the spec, but let's add a sensible null check in the meantime. 2024-03-11 09:35:35 +01:00			`<script src="../include.js"></script>`
