AIOHTTP: WebSocket client accepts compressed frames without negotiated permessage-deflate

SummaryThe client accepts and decompresses frames with the RSV1 bit set even when the permessage-deflate extension was not negotiated. ImpactA client may unexpectedly decompress WebSocket frames when explicitly opted out. This could lead to additional CPU/memory consumption, but is unlikely to be...
