🐞 bug report

Is this a regression

No, I have seen no versions where this works as expected. We were on ngx-mask 13.something and upgraded to 16.4.2 to see if the problem went away.

Description

A*@A*.A* is allowing values such as abc@a - for some reason the literal dot is never required. If you use an exact A*@A*.AAA, all is good, but this will not work for .ky for example. If you try to do something like A*@A*.AA||A*@A*.AAA||A*@A*.AAAA, only the first mask seems to be valid.

🔬 Minimal Reproduction

I have created a stackblitz on Angular 18 (this happens on Angular 15 as well in our local project) https://stackblitz.com/edit/hmpuzh?file=src%2Fexample%2Fform-field-overview-example.html

In this example we have added a new pattern to allow more than alpha and numeric for the email, but have an example at the bottom using just the pattern A that is out-of-the-box.

🔥 Exception or Error

No error - problem with behavior and for being valid when it should not be

🌍 Your Environment

Angular 18.1.2 on example in stackblitz ( we are also experiencing this on Angular 15.2.10)

does not appear to be browser specific

I do not believe OS or IDE matter.
