Re: [csswg-drafts] Resize Observer spec and Blink's implementation disagree on what happens when the writing-mode changes (#3887)

I would suggest a `Note` below the `isActive()` documentation here:
https://drafts.csswg.org/resize-observer/#dom-resizeobservation-isactive

...perhaps saying something like the following:
"Note: in the above comparison between `currentSize` and `this.lastReportedSize`, the two sizes may have been captured under different writing modes (in which case one size's `inlineSize` would be a width whereas the other `inlineSize` would be a height).  User agents should not concern themselves with this difference of writing-mode in the equality comparison -- a user agent should simply compare the two `inlineSize` values for equality, and the two `blockSize` values for equality."
