What is the current behavior?

If a suffix such as .sh is added to the mask, and the first character a user inputs(e.g. h) is the last letter of the mask(e.g. .sh) it will not allow the character(h) to be inputted.

Issue Number: 943

What is the new behavior?

If it is the first character inputted, the assumption is always that it should be added to side step includes logic. All existing unit tests currently pass.
