Description

Initial event logging on Wikifunctions production includes only 2 values of viewname for event name wf.ui.newView.mounted: 'function-editor' and 'function-viewer'. We also expect to see values 'function-evaluator' and 'default-view'. We need to understand why those values aren't showing up.

There is related info in T342667.

The relevant Metrics Platform instrument, in App.vue, is this line:

this.dispatchEvent( 'wf.ui.newView.mounted', customData );
