Details

Currently, FindBoundary returns the start or end of the document (depending on the search direction) if no boundary is found. While this is intended behaviour, it can result in infinite loops in calling code; e.g. bug 1825054. It might be more "obvious" for an invalid point to be returned instead.

This would require changes to HyperTextAccessibleBase and Mac text code.
