[James Teh [:Jamie]]

I guess the DocAccessibleParent gets destroyed after the RootAccessible here. We either need to get rid of the assertion, check for the SessionAccessibility first or forceably destroy any DocAccessibleParents when the RootAccessible gets destroyed. The third solution would probably also solve bug 1778585.

Comment 5

[Eitan Isaacson [:eeejay]]

I don't think this is a duplicate of bug 1778585. There indeed the problem is that the DocAccessibleParent is unregistered (because the root shut down), but is not destroyed itself and therefore can allow show events.

This case is more troubling because it suggests that the DocAccessibleParent failed to unregister in the bulk-unregister that should have happened when the root went away.
