Mask Initialization Issue: Extra Digit Added During Initialization

[Gerakl22]

Describe the bug During the initialization of the input mask, an extra digit is being added. Specifically, when the mask is configured as 7-999-999 and the initial input value is 7-7__-___, after initialization, the value becomes 7-77_-___. This behavior is unexpected and seems to indicate a problem in the mask initialization process.

To Reproduce Steps to reproduce the behavior:

1. Configure the input mask with the following settings:

   
   const maskConfig = {
      mask: '7-999-999',
   };

2. Initialize the mask with an initial value of 7-7__-___.
3. Observe the value after initialization, which changes to 7-77_-___.
4. Expected behavior The value should remain 7-7__-___ after mask initialization.

If your mask includes fixed digit 7, I'm pretty sure you should set value of your input field without it in mind i.e. if you want the result to be 7-123-456, you should set your value to 123456. I believe this is intended behavior.
