        # When the #wiki_content textarea is filled in, JS captures the `Enter` keydown event in order to do
        # auto-indentation and manually inserts a newline. However, for whatever reason, when you try to click on the
        # submit button in Capybara, it will not trigger the `click` event if a \n or \r character has been manually
        # added to the textarea. It will, however, trigger ALL OTHER EVENTS, including `mouseover`/down/up, focus, and
        # blur. Just not `click`. But only when you manually insert \n or \r - if you manually insert any other sequence
        # then `click` is fired normally. And it's only Capybara. Browsers and JSDOM don't have this issue.
        # So that's why the next line performs the click via JS.
