Invalid CSS in Google Maps Plugin

Hi.

Just letting you know that there is invalid CSS in this file: wp-content/plugins/wpmu_dev_maps_plugin/css/google_maps_user.css

...on line 4. background-color is set to "none" which is invalid code and causing the markers and location information flags, etc to have blocky white backgrounds. The CSS should read...

background-color: transparent !important;

You're welcome
