I knew about this for years, didn't realize it wasn't common knowledge.
Didn't know Chrome returns an array until your article.
That is what's truly insane. They literally added extra logic to process invalid HTML differently, instead of assuming valid HTML and bailing after first match.
Which means that doing new Vue({el: app}) new Vue({el: '#app'}) will suddenly start failing (and only in Chrome) when someone makes an inner component that has an unfortunate #app id as well.
