[hirokiky]

Proposed Changes

• Migrated BSkeleton to Vue 3 functional component as function
• Vue 3 won't allow to return empty values, so now it will return CommentVNode when deactivated

I refered ModelList.vue changes for this commit

@hirokiky Thank you for your PR!

Could you git rebase your branch on top of the latest dev? It should not cause any conflicts. Sorry for confusion, but we have changed the workspace structure from main.

@kikuomax Thanks for your review!
I fixed it, but is it OK? If it's not, I'll create new Pull-Request.

@hirokiky Thanks for the updates. I remember functional components will cause a problem in production unless we carefully treat them. Could you also update the following line?

buefy-next/packages/buefy-next/src/components/skeleton/index.js

Line 7 in 4905bd9

registerComponent(Vue, Skeleton)

Like I did in:

buefy-next/packages/buefy-next/src/components/menu/index.js

Lines 10 to 12 in 4905bd9

	// explicit `name` is needed to avoid name mangling of
	// Functional Component in production
	registerComponent(Vue, MenuList, 'BMenuList')
