This PR introduces a check on the validity of a SubString range before returning, fixing an ArgumentOutOfRangeException where these values do not correctly reflect the situation.
Root Cause of the Issue
In VoiceOver the text gets automatically deselected shortly after activating. The corresponding SelectionLength is not updated correctly. When this value is then used for a substring a crash occurs, as it becomes out-of-bound.
Description of Change
A check to ensure the substring value is within range. If not an empty string is returned, which is then handled by existing logic.
Issues Fixed
Fixes #324
