Media player icons are inaccurate to other forms of skipping
I'm going to assume this is a limitation in MPRIS, but when using an application that skips forward or backward in time such as a podcasts app* instead of prev/next track, the icons don't reflect the action about to be taken and remain the skip track icons.
Presumably we can't update the playing widget to display icons more relevant to the action of these sorts of media apps.
