Decode as... doesn't work, what am I missing?

I'm doing a capture with SSH remote capture, which all works fine - normally. I'm trying to decode HTTP traffic on a non-standard port.

So I've clicked on the TCP row, gone to Decode As... and added the destination service port as the TCP Port number to match, and set the Current value to HTTP, then saved. Nothing changes.

I've tried on another computer, with a new install of Wireshark, I've blown away my local preferences, no avail. I feel like I'm doing something really, really dumb here, but it's simply not working.

Can you update the question with output of wireshark -v or copy the text from Help->About Wireshark:Wireshark tab.

There is a sample capture attached to 19723: Problem to Decode 5GC-N7 HTTP for payload Application/JSON with HTTP on TCP port 87.
