Experimental: Add support for select placeholders in :placeholder-shown
We still need to account for the scenario where the placeholder is valid, but the placeholder is not selected.
Select element is the element that should matched. This change has been made, along with properly invalidating the :placeholder-shown if another non-placeholder option is marked as selected.
It seems that after over a year, browsers still don't do this... 😖. I wonder if they ever plan to support this. We will continue to hold until this is actually supported by someone indicating this is actually starting to be adopted.
This functionality seems to have been moved to :blank in the spec. Closing as it seems this will not be relevant to :placeholder-shown.
