Ractive.components global

Hi, thanks for great plugin.
I have component defined in Ractive.components:
Ractive.components['Selectize'] = extend...
but, when ractive-load run into 
`<rel href="Selectize" > 
`
he will load same component again (only first time).

How can I force ractive-load to first check is component already defined at global Ractive.components ?
