There's an unload event listener here: https://searchfox.org/mozilla-central/rev/9c6e7500c0015a2c60be7b1b888261d95095ce27/browser/components/newtab/AboutNewTabService.jsm#225
this prevents about:home / about:newtab from entering the bfcache. Thankfully, this only occurs when the privileged about content process is enabled. It was added in bug 1416066 to, I think, address a potential leak.
Doing some probing and testing though (mainly be just removing the event listener), I'm not detecting any window leaks when I push to automation with that event listener removed. We should just get rid of it.
