ngx-mask with special characters at the beginning

[mnovikovleobit]

🐞 bug report

Is this a regression?

Not sure, but looks like no

Description

If mask starts with a special character (I tested it with braces and parentheses), it will type in the special character on any keypress (characters that are not allowed in the mask itself) and then block all the next ones.

🔬 Minimal Reproduction

ngx-mask live demo
Second mask from the bottom, ALLOW FEW MASK IN ONE EXPRESSION. Try typing any of the characters that are not in the mask.
