 The WP_Block_Supports class is a new addition that will come with 5.6 and
 acts as a register of the kind of features a block supports. It's already
 on WordPress 5.6 beta1 and we need to fix how core and the plugin play
 together in a number of situations:

 - plugin + WordPress < 5.6 (core has a WP_Block_Supports class)
 - plugin + WordPress >= 5.6 (core doesn't have a WP_Block_Supports class)
