Mostly a follow-up to a recently merged PR (#34316) in which I just realized a couple of things were still broken. @siriwatknp let me know about a better way to do the Autocomplete's playground demo work on dark & light mode, as it's using ternary and hard-coded RGBa values (as they're from the branding theme).
