When using dependencies: true the analyzer crawls your module graph to find any third party dependencies to figure out where third party CEM's may be located. It should skip crawling local files though, because they'll already be crawled anyway. We should add a check in find-dependencies next to the builtin modules check to see if the imported file is a bare module specifier.

This shouldn't affect analysis of your CEM, however, the styles file and contents should still be included in your CEM. I checked and verified this locally.
