Progress bar for buffered live streams is not displayed

[snoesberger]

With the Paella 7 player, it is not possible to configure the player to display the progress bar for a buffered live stream.

See also the discussion about this topic in the PR #204 and especially the following comment:

@snoesberger and I tried to bring back the progress-bar for live-streaming video, my assessment is as follows:

• There is definitely a need to have some changes in the player.js file, since the progress bar visibility has been blocked programmatically (which I forgot [sorry about that])
• However, the local tests on my side with this feature ended up with following error, and I was not able to find a single line of help:
  • Uncaught (in promise) TypeError: HTMLMediaElement.currentTime setter: Value being assigned is not a finite floating-point value.
  • Apparently paella 1.46.1 is the answer for that error!
