In the original dev blog from last year they mention it’s still a work in progress.
https://developer.chrome.com/blog/rfc-customizable-select
> Note: The multiple and size attributes on select (<select multiple> and <select size=n>) are not supported in appearance: base-select yet.
From last year while it was a WIP
and now this as of Chrome 135 is shipped, and they didn't think it wise to include a back reference to this post, calling out what isn't supported?
They can and should communicate this is all.
Agreed. Should have mentioned it in this post or at least linked back to my source.
