30738	JS content templates for base WP_Customize_Control	celloexpressions	westonruter	"This will make it possible to create all of the base Customizer control types directly in JS, and will allow them to share a single template passed from the server on Customizer init for all controls with the basic types (following up on #28709).

I think we may need to explore adjusting how register_content_type works since this control handles multiple types and all fallback types. But more likely we'll just do something a bit different, probably adding fallback handling on the other side and hard-coding these types into the Customizer Manager somewhere.

Follow-up to #29572. Related to several tickets I'm currently creating."	task (blessed)	closed	high	4.9	Customize	4.1	normal	fixed	needs-unit-tests has-patch needs-testing has-dev-note		accessibility, javascript, rest-api
