How to prevent numericstepper from setting the value to the defined Maximum when a number greater than maximum is entered in by keyboard and user hits the "Enter" key.

I need to set the Maximum so that the use can use the mouse to change the value of numericstepper (and not go over a certain number), but at the same time I have to allow the user to enter their value by typing in the text field. When the user enters a number greater than the Maximum, I disable the "Ok" button of the dialog and show a red warning(error message). The issue is that the user can hit "Enter" and numeric stepper would set the value to the Maximum and the dialog box would close and the rest of code would run. I want the numericstepper not to change the value and keep showing the warning even if the user hits the "Enter".

Note: Setting maxChar does not help since my maximum is 1000, and user might enter 5555

I would appreciate the help.
