Auto-filling slot containers
Is there a way for an instance added to a slot to automatically fill the slot container? For example, when I insert a row component into the slot, it keeps its fixed width instead of expanding to fill the slot.
Selecting a preferred instance variant
When setting a preferred instance for a slot, it seems like I can only select the base component—not a specific variant. Is there currently a way to choose a specific variant as the preferred instance?
The only workaround I can think of is breaking that variant out into its own component, but that feels like it defeats the purpose of variants.
Am I missing something in how slots are intended to work, or are these current limitations?
