But it doesn't work if you want to allow selectors (or other syntax
sensitive to a lack of white space between tokens) inside the supports
condition. For example with a hypothetical:
@supports (foopy: select(#a/**/.b/**/)) { ... }
There's no way to know that the comment before the "." needs to be
preserved while the one after the "b" can be dropped, if your UA doesn't
implement foopy. So we would need to preserve all comments within the
property value parts of the supports condition, at least.
