getAudioLanguagesAndRoles() in ShakaPlayer returns more than 1 combination for 1 track with accessibility tag

Have you read the FAQ and checked for duplicate open issues? - Yes

What version of Shaka Player are you using? - shaka-player@3.0.7

What browser and OS are you using? - MacOS, Chrome Version 96.0.4664.110

What did you do?

• Received a manifest with an audio tract that contains 'Accessibility' tag and 'Role' tag. Then I've used a getAudioLanguagesAndRoles() method from ShakaPlayer class.

What did you expect to happen?

• I've expected to receive one object per each track, which describes it.

What actually happened?

• I've received 2 objects containing the same 'language' value and different 'role' values, one of it is a value of 'Role' tag in the audio track, other one is a value of 'Accessibility' tag.

We use it to display audio tracks in UI as a picker, but it returns us 2 objects for 1 audio track, which requires us to make some filtering after the getAudioLanguagesAndRoles() method invocation.

Does shaka player have another API for this?

Can you share your stream to see what's happening? I want to see how you declare Accessibility and Role tag to see what we are doing wrong. Thanks!
