Can't override theme for account pages

Permalink 6 6 Browser Info Environment
I'm trying to use the theme paths to override the theme of the account pages and it appears to be impossible to do now in 8.2.1. It worked in 5.7. I thought it might have been just my upgraded site, but I tried adding this to a default install of 8.2.1 downloaded from concrete5.org, still didn't work. The administrators see it as a dashboard-ish page with the dashboard panel, regular users see it using the "concrete" theme.

return [
    'canonical-url' => '',
    'canonical-url-alternative' => '',
    "theme_paths" => array(
        "/login" => "elemental",
        "/account" => "elemental",
        "/account/*" => "elemental"
    )
];
