After opening a mp3 file in a new tab, the audio starts playing. When the space-bar is pressed the playback pauses, and when it is pressed again the playback plays. But when I pause/play the playback with mouse click, the space-bar keyboard shortcut stops working. After this, pressing the space-bar doesn't play/pause the playback. However, once I reload the tab, the keyboard shortcut starts working again. The keyboard shortcut works inconsistently. Please help.
