Description

when a text field has the following validation:

fields.text({
  label: "Twitter",
  validation: { isRequired: false, pattern: { regex: /^@.+/, message: "Must start with '@'." } },
})

i had expected that the regex pattern would only be checked when the optional field had a text value, but not when it is left empty.

Research direction

Start at the fields.text API and its validation handling, using the example to reproduce an optional field with an empty value and a nonmatching value. Done means an empty optional text field bypasses pattern.regex while a supplied value is still checked.
