The Save Search action link is correctly disabled when the current search has already been saved, and it can be clicked otherwise.

I just want to note that if you erase the text in the search input box, you can still click Save search; however, it will save the last text that was actually searched, which appears to be the intended behavior.

Thanks @LianaHarris360 for the review and for raising this. It looks like we will need to improve the user experience of the save search feature but this should be sufficient for now. cc @marcellamaki
