I noticed that the tooltips for dependencies are not shown in a production build.
That can be reproduced on the advanced angular demo (just use the production build).
I tracked it down to following angular build options:
"optimization": true,
"buildOptimizer": true,
if one of these settings is different (e.g. "buildOptimizer": false) the tooltips are working again.
But the combination these two options prevent the tooltips to be shown.
Unfortunately, no updates for now. Meanwhile, a known workaround is to disable the build optimizer for production. In angular.json set for the production config:
"optimization": true,
"buildOptimizer": false
