It was made exactly for that purpose, to be able to switch out the html tag underneath

@ncigula @aabney-Tamus @fabianschurz This PR should fix your issues. If you want to confirm, please do so.

@danielchalmers What if we allow up to 20 as the max value of spacings? Because if you used `Spacing="10"` before you got bigger gaps than when you use `Spacing="16"` now,...

The old grid used `8px` as the spacing unit?

Thanks @danielchalmers Added this to the migration guide 

It is a bug yes, but we don't have a solution at the moment as nobody wants to touch popover ;). Somehow we'd need a solution to pass a root...

Actually it is planned to fix this in the future by replacing our popover with a library that is capable of doing this, so maybe we should keep it open...
