1492134 - Video element shows an empty label for tracks if label attribute is missing

Status: NEW

(Core :: Audio/Video: Playback, defect, P3)

Description

[salvan13]

Attachment: a menu item has not labels

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:62.0) Gecko/20100101 Firefox/62.0
Build ID: 20180830143136

Steps to reproduce:

open https://developer.mozilla.org/en-US/docs/Web/HTML/Element/track
and check the video in the preview


Actual results:

The list of substitles ("cc" button) contains two elements: "off" and an empty element,
if the track element does not have a label attribute the element is empty


Expected results:

I expect some text there, maybe it can be the value of srclang attribute if the label is not present (like Google Chrome do), or something like "track1"

Hello,

I was able to reproduce this issue on Windows 10 / Mac OS 10.12 / Ubuntu 18.04 using 
FireFox 62.0 (20180830143136), FireFox Beta 63.0b7 (20180917143811) and FireFox Nightly 64.0a1 (20180920220102).
I'm setting a component in order to involve the development team to review this issue.

Thank you for reporting!
