This happened to me throughout the years as well, but it's really a minor issue.
However, I might still suggest the options to add a "Show Volume Slider" and a "Show Play Duration" to the player controls panel for more customizing options. I'd use them, especially the latter option, for aesthetic reasons since the font size of the duration can't be changed on the fly ((hovering) the progress or wavebar as an indicator is enough in most cases).
