30694	Document FileResponse does not seek its file source	Claude Paroz	nobody	"I'm not sure this is a bug, but I was bitten by some code today:

{{{
buffer = io.BytesIO()
buffer.write(b'some binary content')
return FileResponse(buffer, filename='somename.bin')
}}}
and the response is empty because the stream position is at the end of the buffer. I can easily fix that by seeking the buffer myself, but shouldn't `FileResponse` seek itself in `_set_streaming_content` before calling `filelike.read`?"
