Unhandled ArgumentOutOfRangeException in Edit.Dialogs.FrmFindDialog (count less than 0)

Steps to duplicate:


  1. Open Find dialog and search for a string with "Find Next" (at least one occurrence must be found in the document).
  2. Ensure that the "Match Whole Word" checkbox is checked.
  3. Search for any string with "Find Next".
  4. This will result in an unhandled ArgumentOutOfRangeException indicating count is less than zero, and the application will terminate.
This occurs reliably in version 20.4.0.38 and in 18.4.0.30.  Since I have no access to the source code for the Find dialog within the Edit control, I can neither catch this exception, nor modify the source to avoid it.

My application is targeting .NET framework 4.7.2
