Fatal error when using prebind #1502

I am using prebind authentication. When I initialize converse, I receive the error "FATAL: TypeError: Cannot read property 'insertAdjacentElement' of null" that can be traced back to converse-register.js:57, where this.el.querySelector('.buttons') is set to null because, presumably, the querySelector function cannot find any elements. This error occurs when using prebind authentication but not login authentication.

I am writing it here on github because the lack of a clear error message that describes the problem on the user's end is something that ought to be resolved.

Did you modify any templates or change the code in any way?

No, I have used a fresh install of converse and have included converse.min.js and converse.css in the html file. Here is the converse.initialize script:

    locales_url: 'apps/view/javascript/converse/locale/ro/LC_MESSAGES/converse.json',
    bosh_service_url: 'http://localhost:5443/bosh',
    debug: true,
    prebind_url: 'http://localhost/index.php?[query string not shown for security reasons]',
    authentication: 'prebind',
    allow_logout: false,
    keepalive: true,
    message_carbons: true,
    play_sounds: true,
    roster_groups: true,
    show_controlbox_by_default: true,
    xhr_user_search: false

Note that I am also getting another error afterwards:

Uncaught (in promise) Error: restoreBOSHSession: tried to restore a "keepalive" session but we don't have the JID for the user!
    at Object.restoreBOSHSession (converse-core.js:1059)
    at Object.attemptPreboundSession (converse-core.js:1081)
    at Object.logIn (converse-core.js:1183)
    at D (converse-core.js:423)
    at Object.T.initialize (converse-core.js:1226)

EDIT: prebinding works fine using another client, jsxc, so my prebind link isn't the reason for the error.

EDIT2: using cdn-supplied .css and .js files produces the same error.
