Using web components in a Mesop app requires a lot of repeated configuration

When using web components in a Mesop app, we need to make sure to add the appropriate stylesheets and CSP security configurations each time for each app.

It could be nice if the web components could be configured with some of the CSP configurations required to get it to work. Then we can merge into the page security policy.

Stylesheet would be good too, though I guess there are cases where one may want to use a different style sheet like in the markedjs web component where we load a stylesheet for the code highlighting and there are different themes to choose from.
