Subject: [PATCH] gui: Use indexOf instead of startsWith for IE11 compatibility
 (fixes #6940) (#6942)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Use indexOf() == 0 instead of startsWith() to maintain compatibility
and prevent JavaScript error console spam in the Web GUI when used in
Internet Explorer 11 under Windows 7.
