What information was incorrect, unhelpful, or incomplete?

I am working on supporting the listbox rendering mode for customizable select, which allows appearance:base-select to work on <select multiple> and <select size=4>. This will be shipping somewhat soon in chrome.

• Define base appearance for list box select elements whatwg/html#11758
• https://chromestatus.com/feature/6222145025867776

This does not make appearance:base-select work on multi-select with a dropdown, which you get by doing <select multiple size=1>. That will be worked on as a follow up.

What did you expect to see?

This should be documented in the customizable select article, and possibly the main select element page if applicable.

Do you have any supporting links, references, or citations?
