Is it a bug at PassThruResponseFilter::Filter function?

[luodijia]

The PassThruResponseFilter::Filter function is at the cef\tests\cefclient\browser\response_filter_test.cc.If the data_in_size is more than the data_out_size, should the data_in_read equals the data_out_size? It means that data_in_read should equals the data_out_written, otherwise it'll lost some data. Because you read more but write less. data_in_size > data_out_size is possible in some case

The expected behavior is documented on the CefResponseFilter::Filter method. There's also https://bitbucket.org/chromiumembedded/cef/issues/2282
