I have a guess as to why this fix was delayed—on the release candidate, you weren't able to resize windows in Stickies. I filed a bug for it. This felt like a last-minute addition—the previous betas didn't have the 'fix.'

Let's think about why: if the width of the handle is based on the radius, and the radius is 0 for a window, there's nowhere for the grab handle to be.

I assume this wasn't the only app with fully square windows, and so the fix actually caused more problems. Respinning a release candidate is expensive, and they were out of time for this one. So the patch gets reverted and the fix gets iterated on for the next release, where they'll presumably figure something clean out that's conditional on exact window shape.

26.4 could be the spring hardware release or it could be the spring services release. I would give it a 2/3 chance of landing in 26.4, and a 1/3 of being moved to 26.5.
