[Glimmer] willDestroyElement is sometimes called again when the outlet view destroys the toplevel view

[krisselden]

I noticed this failing a unit test during App.reset() so this reproduction is based on that.

There are other cases of it during a route transition that I haven't made a reduce reproduction yet. Just wanted to track this.

@krisselden - Any progress/updates on tracking this down?

Added test for ensuring childViews is maintained when render nodes are removed: https://github.com/emberjs/ember.js/compare/child-views-maintained.

the above illustrates the issue with childViews and willDestroyElement being called twice.

Any progress?

Encountered this this evening (via ember-wormhole), it quickly spirals into deathly recursion :'(
