Negative margins are not compatible with hover

[laurencei]

If I modify the modules section of my tailwind.js to add hover support to margins:

margin: ['responsive', 'hover'],

Then I can do this:

hover:mt-1

But this does not work

hover:-mt-1

I'm guessing because of the leading - is causing an issue?

Turns out there is also a negativeMargins module:

negativeMargin: ['responsive', 'hover'],

Problem solved.
