PiP Pause/Play Bug

When enabling the PiP player window for say a YouTube video from the YouTube website - pressing the 'pause' button on the PiP player window followed by doing any forms of multitasking like opening another window, or opening another program/app or file etc, and then a few seconds later pressing the 'play' button on the PiP player window - it doesn't actually play the video. You can click the 'play' button over and over and over again but the video in the PiP player window will not play. In order to get the video to play again you have to exit the PiP player window by clicking 'back to tab' and then clicking the 'PiP' icon again. Using Firefox version 115.0.2 Anyone else experiencing this?
