This is intended to prevent multiple players (using a single browser)
from accidentally seeing a name that a previous player entered when
the browser offers it up for autocompletion.

<label for="character">Character name</label>
- <input type="text" id="character" required>
+ <input type="text" id="character" autocomplete="off" required>
<input type="submit" value="Join game">
