Not all the test targets are properly split up. For example, web_view_interaction_test_util.h is in earl_grey_test_support, when this should not be tied to EarlGrey.

There are likely a few other cases (there was one with wait_util being dependent upon EarlGrey). Where a file that doesn't have to do with EarlGrey (or the web shell), but is in a target that couples it to it.
