With the release of the new Javascript API 4.24, Calcite components are not being displayed and rendered properly in the popup. Upon inspection of the DOM, all calcite component tags have been cleared/removed and only the text of the components is being displayed. It was working fine with the 4.23 version of the JS API, so unless I'm missing something when setting the content for the popup, I'm suspecting this is a bug. I've tested it in the Sandbox samples too and getting the same result.
