Phone number phone component doesn't tell user how to format phone number, leading to submission failure

[twoangstroms]

No hint text in text entry field but form rejects phone number without specific entry format.

Instead of "Phone Number" as hint text, show (555) 555-1212 if that format is required. I entered 5551212 and the form failed, but had to guess that 555 5551212 would work.
