Client-side validation is being skipped because it reads .text() instead of .val() from the telephone input

Issue summary

After enabling webform_intl_tel_national_mode, the improved national-mode UX works, but client-side validation appears to stop working.

Example:

• enable Webform telephone international mode
• enable webform_intl_tel_national_mode
• enter obvious invalid input such as letters
• submit the form

Actual result:

• no validation error is shown
• invalid values can pass client-side validation

Expected result:

• invalid values should still fail intlTelInput('isValidNumber') validation

Root cause

In the module’s JS override:

[webform_intl_tel_national_mode/js/webform.element.telephone.js]

the validation guard uses:

if ($telephone.text().trim()) {

But $telephone is an , so .text() is empty. For input elements this should be .val().

Because of that, the validation block never runs.

Proposed fix

Change:

if ($telephone.text().trim()) {

to:

if ($telephone.val().trim()) {
