mdbInputMask problem with copy-paste value

*Expected behavior*On input text field with mdbInputMask="999-999-99-99" when copy paste value "0123456789" I would expect to see in the input field value like: "012-345-67-89" it means value properly formatted with defined mask.

*Actual behavior*However, the mdbInputMask directive, instead of inserting dashes "-" at particular positions it replaces the digits with dashes what is strange and unexpected because it breaks the source value. From the example above the input field value is like "012-456-89-"
