Issue with Safari 12 for datalist populateoptions

[TaylorPope]

Using safari the option list covers the input box so you cant see what you are typing.
The list comes from populateOptions in datalist.js

We fixed it for our case by adding:

.wb-al-cnt {
  top: 42px;
}

Not sure if this is a good fix or specific to our use. Here is an example pic to see what the issue is:

This appears to be fixed with macOS latest updates. When using http://wet-boew.github.io/v4.0-ci/demos/datalist/datalist-en.html.
