Music playing during edit mode?

Hi! Can someone help me figure out why my Title Screen music starts automatically when I enter Edit mode? It doesn’t happen on other levels, just the title screen. I wouldn’t think any sounds would auto-play while the editing screen is open.

Here’s the link (the game itself is still in progress, so don’t judge!)

I found a similar problem with Capt. Red Crab’s Mario game

And it didn’t happen to me

It sometimes happens to me when the website thinks your playing the game when really your not. I actually have no idea on how to fix it, but it isn’t a rare thing. (At least not to me)

pressing play then edit again usually fixes it.
If not, then refresh your browser.
