So setting focus can trigger a deferred layout that invalidates the associated render element which cause asking axObjectCache() either found no document, or no axObjectCache at that document. I tried removing the element in the test as you suggested, but seemed no luck to crash it. 

Any other suggestion to come up a way to reproduce it in the layout test?

Thanks.
