NPS Bottom Bar - Preview/Next track buttons don't darken when inactive

App version

Production

Issue description

When using the Prev track or Next track buttons in the Bottom Bar, the buttons do not darken on the first/last track. This makes it impossible to tell when the buttons aren’t active.

Device type

Phone

Media provider

Local device

Steps to reproduce

Set up the Bottom Bar to include Prev track & Next track buttons. (Optionally set the Controls bar to also have these buttons for comparison.)

Tap the buttons to go to the first/last tracks in the queue. The Bottom Bar buttons stay the same color regardless of queue position, whereas the Controls bar buttons will dim when the first/last track is reached.

Additional information

Attached GIF shows Bottom Bar Prev/Next buttons stay the same color when on Track 1 vs Track 2. (Prev button should darken on Track 1 but doesn’t.)

Watch the left two buttons:

Note that the Prev/Next Chapter buttons correctly darken when inactive but the Prev/Next Track buttons do not.

Also I have checked with other color themes, which had no effect on this issue.

Both buttons in GIF are set to the same color option. Issue is present on all options (Default, Primary, or Tertiary).

Minor add on: the “Chapters” Bottom Bar button does not darken in the NPS preview for tracks 1 & 3 but correctly darkens in live NPS when no chapters are present.
