[resize-observer] Mangled text for populating ResizeObserverEntry.contentRect?

[Loirooriol]

https://drafts.csswg.org/resize-observer/#create-and-populate-a-resizeobserverentry has this step:

6. Set this.contentRect to logical this.contentBoxSize given target and observedBox of "content-box".

This looks unintelligible to me.

I suspect the «given target and observedBox of "content-box"» was copy-pasted from the previous steps but it shouldn't be here.

And I guess the idea is turning the ResizeObserverSize stored in contentBoxSize into a DOMRectReadOnly.
