- <h1>Description</h1>
- <p>
- This test validates that PerformanceResourceTiming.decodedBodySize correctly reports
- the size of resources after removing content encoding (gzip, brotli, deflate, and
- compression dictionaries with dcb and dcz), and that it differs from encodedBodySize
- for compressed resources.
