(49.7KB, 412x507) Thanks for reporting. On my phone there is this close button on the form so I didn't know this was an issue once the screen gets too thin.
I'll work on fixing this tomorrow. Until then, rotating your phone to make the page wider will hopefully workaround this problem.
I've added some styling code to show that close button until a screen is absurdly narrow.
(If your browser has cached the styling code, you may not see this fix until you either clear the browser cache or use a private browsing/incognito window.)
