LibWeb: Skip HTMLLinkElement resource fetching for documents without BC Fixes crashing after following steps: 1. Open https://github.com/SerenityOS/serenity 2. Click on "Pull requests" tab The problem was `navigable` null pointer dereferencing in `decode_favicon()`. But navigable is null because the document was created by `parseFromString()` DOMParser API. With this change we skip fetching initiated by HTMLLinkElement if document does not have a browsing context: - Favicon is not displayed for such documents so no need to fetch. - Stylesheets fetching won't affect such document because style or layout does not run for them. 2024-04-24 17:57:18 +00:00			`<!DOCTYPE html>`
