CSS scrollbars

Hi, I noticed that Edge 150.0.4078.65 on Windows 11 does not appear to render the "scrollbar-color" and "scrollbar-width" styles from the https://developer.mozilla.org/en-US/docs/Web/CSS/Guides/Scrollbars_styling. See demo page: https://css-scrollbars-skobescr.yoyo.codes/, where all scrollbars appear in the default style. This surprised me for a couple of reasons:

(1) "Can I Use" claims (mistakenly?) that Edge suppports this feature.

(2) Other Chromium-based browsers support this feature.

I'm curious if this is a regression, a deliberate product decision, or something we may expect to see added in the future.
