Yep, that's the ideal approach for decent browsers. A curious caveat is that IE 8 and below will interpret that example HTML as (ie. as siblings, not parent and child) and therefore not apply any component-scoped styles. Not ideal.

Of course nobody uses those browsers anymore, the same caveat applies to non-custom HTML5 elements, and the bad behavior has long been preventable with JavaScript [0]. But anyone (else) with an extreme backwards compatibility mindset might consider if they could instead bootstrap from

and (if needed and in window) a coordinating MutationObserver.

I feel the same way, although I do struggle with excluding people who use older technology. I suppose TLS 1.2 is fairly old at this point ...

You're not the only one. I block most subresources by default and was disappointed to see empty figures peppered throughout their articles. I'm learning to not automatically equate advocacy of "vanilla" with advocacy of robustness.
