I guess this is how it is supposed to function it just doesn't work in the same way as similar features I've used. The 1.1 link in the popup window could be fixed as the text does not load.
Applied the edits, cleared caches. The tooltop popup is just showing the same text as that which triggers the popup, rather than the explanation. Also, the delete option for the explanation/message returns a 404 for site/warnings.php

#3476 - Warnings issues
The rest will be now visible from popup in tooltip.
However, the tooltip is showing the explanation and message, I'm 100% sure of that.
