1711091 - [Bug] HTML Required attribute breaks if first option has no `value`

Status: NEW

(GeckoView :: General, defect, P2)

Description

[Kevin Brosnan [Ex-Mozilla]]

From github: https://github.com/mozilla-mobile/fenix/issues/19473.

Steps to reproduce

Try to submit a form with a select element that has the required attribute where the first option has no value="".

Demo: https://www.michaelsinclair.com/select_bug_demo.html

Expected behavior

The user should be prompted to choose an item in the list, and the form should be prevented from being submitted.

Actual behavior

The form is prevented from being submitted (as expected), but the user is not prompted to choose an item, leaving them without any context clues as to why the form won't submit.

Device information

• Device vendor / model and Android version: Samsung Note 8, Android 9
• Firefox for Android version: 88.1.3 (Build #2015808507)

Happens on other Android devices and versions as well.

Change performed by the Move to Bugzilla add-on.
