Bug 1781193 - Update table layout-guess and mathML innerHTML on reorder. r=Jamie
This helps on several fronts:
1. Avoids a cache push on accessibles that have yet to be sent to
parent when relying on BindToParent instead.
2. Handles the case of table children removals.
3. Uses the mutation event collation for cache push collation.
No test case for MathML here because it is windows only, but I think
we should add coverage for it too.
