Subject: [PATCH] Fixes submit event of the search input

In HTML, when a button follows an input, if the enter keep is pressed on the input, instead of sending the submit event to the input, it'll create a click event on the button following it, which in this case made the help popup show up whenever "enter" was pressed.
