I hate when things pop up when I select text, because I have a tendency to randomly highlight text as I'm reading it.

This little speaker pops up, so I clicked it out of curiosity, and it started to speak the text. The icon choice is a little unusual (I'd expect a play button or something, but that icon is typically used to control volume). But then I couldn't get it to stop playing. I even closed the tab and it was still playing. And for some reason Chrome doesn't show that tab as even playing audio so I could mute it. What the heck is going on there?
