A DESCRIPTION OF THE PROBLEM :
In the method queryAccessibleAttribute of the class Control the tooltip text is used as accessible help if the help text is not provided. This leads to accessibility bugs. Assume you have a cell with a string in it and you add a tooltip with the same text. This allows you to show the text even if it is truncated. Then the accessibility interface should handover the cell text as accessible text for a screen reader. However, because of the tooltip additionally the accessible help is set. According to accessibility norms the help text should give additional information only. Additionally a screen reader may read out the accessible text and help which means it doubles the same information.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a ListView of Strings with an item and overwrite the cell factory to create a cell with tooltip. Then on Windows show the application and check the cell with "Accessibility Insights for Windows". The properties Name and HelpText have content even though only the Name should have content.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The accessible text or in "Accessibility Insights for Windows" the property Name is set.
ACTUAL -
The accessible text and the accesible help or in "Accessibility Insights for Windows" the property Name and the HelpText are set to the same value.
