Fix validation not being applied

Fixed with 🐛 Doesn't work with multiple phone fields Needs work .

Need to verify this indeed has been fixed.

I created this ticket based on #3302638-3: Telephone International Widget 2.0.0 stable release plan → . I assumed the front-end validation from 🐛 Doesn't work with multiple phone fields Needs work was sufficient, but I realize now that this is referring to back-end validation.

I was able to reproduce this issue. Digging.

I realized that this should be marked as a feature request, not a bug. To fail validation and prevent save might even be considered a breaking change. Though, if the community wants this, we could add it to a release candidate before making it to 2.0.0. Perhaps even make it configurable.

Moving this out of 📌 Release 2.0.0 Needs review , unless someone objects.

@plopesc pointed out that this feature may already be addressed by Telephone Validation → . I wonder if @omkar-pd might be willing to share reprucible steps if this becomes an issue with the modules not playing nicely.
