[A11y] Support spaces in IDs used for aria-activedescendant
Spaces in IDs aren't legal HTML, but authors still use them, and they are supported for some other APIs like getElementById(). Prior to https://crrev.com/c/5836703, they were also able to be used for aria-activedescendant attributes, which only take a single ID, and authors have depended on this behaviour.
This change restores the old functionality, and adds a regression test.
