Currently the
ɵEmptyOutletComponent
is very prone to generating ID collision warnings with user code, because it only has one child and no other metadata. This shows up some of our tests as well. While users can resolve it on their end, it can be confusing since they won't have any references toɵEmptyOutletComponent
in their own code.These changes add an
exportAs
to it to make its component ID unique. This doesn't affect the public API of the component since users can't use it directly anyways.
