Firefox error with link validation regex patterns

+1, having this issue too.

I had this issue in 4.1.1 and @bob.hinrichs is right.
Here's a patch with that change, the errors are gone and seems to be working fine.

joe_carvajal → changed the visibility of the branch issue/clientside_validation-3365957-fix-regex-pattern to hidden.

I created it as a merge request also.
First time doing it this way for a contrib module, not sure if this is done well

@Joe can you please create MR? Check https://www.drupal.org/project/clientside_validation/issues/3504340 🐛 Client side jquery validation module settings page broken Active for example

@Joe - Thanks for the contribution, this is working great for our team. Created the MR for this so we can hopefully get it merged soon.

Thanks everyone
