Progress of Portal? Here are some suggestions.

In the early Vue 3.0 trailer, adding Portal component to Vue 3.0 was mentioned. But it seems that the corresponding RFC has not yet been created.

I have a project that is highly dependent on the portal component. Although the portal component is implemented by myself, but the functionality is similar to portal-vue. And encountered some similar problems. I don't know where I can share these issues.

• Breaks provide/inject: Breaks provide/inject LinusBorg/portal-vue#126 . Portal may cause all mechanisms related to parent-child communication to fail. So it is important to allow mutual access between the portal and the portal-target. And the functions related to communication between the parent and child components also need to take these issues into consideration.

• Vue-devtools support: The actual components that are mounted cannot be displayed in the children scope of portal-target. If there has a redirect or a mirror, it would be great.

Portal is a very useful feature, especially for scenarios like multi-tab code editors. But it requires some underlying compatibility of the framework to work perfectly. I will be very happy to see it become a built-in feature of Vue.

You're right, Portals aren't mentioned in any RFC yet (unless I missed something), but the are coming. We already have evaluated the possibilities in our prototyping.

The limitations that you mentioned and we currently see in portal-vue are simply due to missing support for portals on the virtual-dom level. Since in 3.0 we will add Portals to the virtualdom re-implementation, those won't be concerns anymore.

@yyx990803 I think we should decribe how the basic implementation is going to work, maybe in #28 ?

@LinusBorg I think Portal should have its own RFC since it would be usable in templates too.

re implementation: it's already working in the prototype.

FYI: I'm currently writing up the RFC for this.

@LinusBorg any news?
