Zstd decompression is not supported for HTTP and HTTP2 in the 4.2.x and 4.4.x branches. It has been added to the current master branch and will be available in the next major release https://gitlab.com/wireshark/wireshar...

Unfortunately the expert warning is unclear, and I believe has different behavior compared to HTTP/2. It doesn't clearly distinguish between "that decompression method is unsupported," "that decompression method is supported but not compiled into your build," and "that decompression method is supported but decompression failed due to errors."
