The metronome on the tools page doesn't work properly for me. It launches in a separate window, and starts, but no sound. If I choose a different tone from the drop down, the sound will play once or twice then stop.Likewise, if I change the beats/measure, it will play a single measure then stop. The visual indicator still works - the little "leds" light up - but no sound.

I've tested this in both Firefox and Edge Chromium - same results. Wondering if this is a known problem, or if it works properly for others.

(I do have a simple metronome app on my phone, and I bought a physical metronome also, but it would be nice to have this one available. It looks like it has some good features.)
