LPS-46628

This is an update for [LPS-46628](https://issues.liferay.com/browse/LPS-46628).<br><br>
Hey Rob, I decided to stick with using the attribute selection to get the submit button.  A couple of reasons:
- In this context, it is the only submit button in the navbar scope
- The searches for each tab actually come from different taglibs, so I wouldn't necessarily be able to just use a single id as a catch-all.
