Fixes #208
Empty
props.class
wouldn't be truthy, resulting inclass
being added to the element twice as outlined in the attached issue.The added test might be a bit overkill, but it seems Mocha has no support for test isolation. Importing
preact/compat
(even in other suites) would throw off one of the existing tests, so I just run the compat suite subsequently. Let me know if there's a better way to go about this.
