Previously, when loading a document, we would try to sniff the MIME type by reading from the response body's source. However, for streaming HTTP responses, the body source is Empty (the data comes through the stream instead), so we had no bytes to sniff. This caused pages like hypr.land (which sends no Content-Type header) to be misidentified as plain text instead of HTML, since the MIME sniffing algorithm would receive zero bytes and fall back to the default type. The fix captures the first bytes of the response body during fetch, storing them on the Body object. These bytes are the "resource header" defined by the MIME Sniffing spec - up to 1445 bytes, which is enough to identify any MIME type the spec can detect. Since bytes may arrive asynchronously during streaming, we use a callback mechanism: if bytes aren't ready yet when load_document() needs them, it registers a callback that fires once enough bytes have been captured (or the stream ends). The flow is: 1. FetchedDataReceiver receives network bytes, buffers them 2. When Body is created, buffered bytes are flushed to Body's sniff buffer, and subsequent bytes are appended as they arrive 3. Before calling load_document(), Navigable waits for sniff bytes 4. load_document() passes the bytes to MimeSniff::Resource::sniff() |
