Possibly refactor InlineBlockTest.php

I ran in to InlineBlockTest as and also wondered why it's a FunctionalJavascript test. Looks like there are a few other tests using the same base class that probably don't need javascript either. Possibly we need to keep some of this using WebDriverTestBase but there is so much of this that could move to BrowserTestBase.
