At KDE Connect we had some visual glitches whenever the plasma browser integration reported playing or paused. The cause was that the player was already signalled as paused, but canPlay was not signalled as true yet.

This diff fixes the issue by just always reporting true. This is also what the specifications require (see https://specifications.freedesktop.org/mpris-spec/latest/Player_Interface.html#Property:CanPlay)

The glitch never appeared for me, but the code compiles and works fine with this change.
