Implement trusted types for remaining attribute sinks #38784

TimvdLippe · 2025-08-19T16:12:20Z

Additionally, several methods were updated with
spec comments. That's because the "adopt the document
from the element document" step was missing.

By adding these spec comments, I also restructured
some code to avoid duplication of mutation records
and custom element reaction queueing.

Node.textContent doesn't propagate the error yet,
as that method has a lot of separate callers of
elements that wouldn't fail. I will refactor those
in a follow-up PR to keep things manageable.

This implements part of the DOM integration from
whatwg/dom#1268

Part of #36258

⚠️ Try run (#17077138657) failed.

Additionally, several methods were updated with spec comments. That's because the "adopt the document from the element document" step was missing. By adding these spec comments, I also restructured some code to avoid duplication of mutation records and custom element reaction queueing. Node.textContent doesn't propagate the error yet, as that method has a lot of separate callers of elements that wouldn't fail. I will refactor those in a follow-up PR to keep things manageable. This implements part of the DOM integration from whatwg/dom#1268 Part of servo#36258 Signed-off-by: Tim van der Lippe <[email protected]>
