Log Message:
-----------
DecompressionStream should output valid data before throwing for extra
trailing bytes
https://bugs.webkit.org/show_bug.cgi?id=307952
rdar://170439927
Reviewed by Youenn Fablet.
Per the Compression Streams spec, when decompressing data with extra trailing
bytes
after the end of the compressed stream, the decompressor must:
1. Enqueue the valid decompressed output first
2. Then throw a TypeError
Previously, WebKit threw immediately upon detecting extra bytes, discarding the
valid output.
