"Update the overlay area information" is not well-defined

[yoavweiss]

Update the overlay area information doesn't indicate processing model steps, but says in prose what should happen when. That's not great.

What you want is to define what the "title bar area" is, hook up a resize algorithm for it, and then call this algorithm from there. Then you want this algorithm to be specific:

• The env variables need to be stored on an object (Document or Browsing Context, probably?)
• Then this algorithm needs to change them, and the CSS processing model needs to read them off of this object.

https://wicg.github.io/window-controls-overlay/#update-the-overlay-area-information is an improvement. At the same time, it's not yet clear when this algorithm is called.

Oooops, left a comment on the wrong issue. I think this was further updated, though?

@inexorabletash Hola Joshua, yes, I had a meeting with Yoav and ironed out the problems. The new changes, (including the monkey patch to CSSOM) should be live very soon.

It's now called from https://wicg.github.io/window-controls-overlay/#dfn-title-bar-region-resizes Closing.
