The pattern attribute may contain syntax that does not work with data binding syntax

[ECorreia45]

The following will break the component

<input type="password" id="pwd" name="pwd"
  pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,}"
  title="Must contain at least one  number and one uppercase and lowercase letter, and at least 8 or more characters">

This is because it tries to resolve {8,} thinking its a data binding.

We need a way to handle such cases when we have regex or something similar.
