I've run into it a few times with mine (2017 15" MVP, 3.1GHz Quad i7, 16GB RAM, Radeon Pro 560). I had an issue the other day where a virtual machine got stuck in a loop while testing some background jobs. Each time I tested it, another infinite job booted up. Eventually, I had like 30 of them running when I took off my headphones and heard the fans. Checked my battery and I was down to 65% despite being plugged in. I'm guessing that happened over the course of an hour or so.

I've also had it happen a few times when running unit tests for a different project in Docker, but that's likely just because Docker for Mac makes Electron look resource efficient.
