They must have carefully curated the "general browsing" to sites that do not cause it to crash, as it always seems to pull a vanishing act if the site isn't coded specifically to avoid known crash points. The most reliable way I've found to crash it is to use MutationObservers in a website. Even though Edge has support for them, I still have to pave over it with a JS version that doesn't cause the browser to crash after a few minutes of use. Something is wrong if emulating browser features in JS leads to a better experience than using the feature as built in. Having to do so probably eliminates any battery life gains they have made.
