Fix selection after char removal

Generally speaking, removing a char placed just before mask char resulted in misplacement of selection indicator. 

Consider the setup below:
mask: ###-###-###
hint: 123456789
Your input: 123456789

Error:
Removal of '6' char resulted in selection set after mask, on '7' char instead of '5' char.
