Re: [css-houdini-drafts] [css-typed-om-1]Manual definition of the map entries for StylePropertyMapReadOnly contradicts Web IDL

As a simple example, because there is no infra ordered map involved, and because ES maps only store ES values, the actual values stored are ES Arrays.  Presumably created in the global of the StylePropertyMap.

So when https://drafts.css-houdini.org/css-typed-om-1/#dom-stylepropertymap-append step 8 wants to append to the array, that needs to be defined very carefully, because this is a page-observable operation that can trigger side-effects in various different ways depending on how it's defined.
