There was a problem hiding this comment.
Note that aria-labelledby supports passing a list of IDs so we could've also used all the IDs here, but I think that for the dialog case it makes sense to only have one label at a time.

Currently the dialog assigns the ID of the title as the `aria-labelleledby` of the container, but it doesn't update it if the title is swapped out or removed. These changes add a queue of possible IDs that the container can use as titles are being created or destroyed. Fixes angular#27599.
