IMCE Not kicking start onblur event when using OS X browser.

Hi guys,

The fix on #1334378 seems to prevent ICME from showing the uploaded file on Mac browsers.

Line 116:

'onblur' => "if (this.value.length > 0) { jQuery('#$select_id').triggerHandler('mousedown'); }",

Not kickstarting on any OS X browser. Cannot countercheck on other OS.

Thanks.
