 I tried turning off JavaScript in my browser (via DevTools in Chrome) and
 then activated each core theme to see if I could access mobile nav menu
 items. Unfortunately, for the themes which have an expandable mobile nav
 menu, the majority fail to gracefully degrade when JavaScript is disabled
 (either on purpose or the script fails to load over the network).

 Themes which gracefully degrade by just revealing all the nav menu items:

 * Twenty Nineteen
 * Twenty Seventeen
 * Twenty Sixteen

 Themes which show a mobile nav menu button which does nothing when tapped:

 * Twenty Twenty (mobile search also broken)
 * Twenty Fifteen
 * Twenty Fourteen (mobile search also broken)
 * Twenty Thirteen
 * Twenty Twelve
