Metric dashboard empty bug

Hello, trying to configure the metrics dashboard on the gateway but the page is blank and the ‘add metrics’ button also brings up no configurable values.
Running version 8.1.44

Any errors in the gateway's logs, or in the browser console when you're on this page?

none

We can reproduce this issue in containerized Ignition instances on Chrome and Safari. We’ve confirmed it on versions 8.1.37 and newer, though it may have been present earlier. Network inspection shows that the metric JSON payloads are returned successfully, but they aren’t rendered in the UI.
