Unable to control the order Dashboards are displayed by the Wallboard Slideshow

Expected behavior

Disabling the "random mode" of wallboard slideshow will make the slides appear in a pre-defined order.

Actual behavior

Slides will be displayed in a random order, however, it will keep that order for subsequent loops.

Steps to reproduce

1. Setup the Wallboard Slideshow to display at least 3 dashboards;
2. Start the Wallboard Slideshow;

Additional Notes

Thanks Johnny for sharing the outcome of the below steps.

• Refreshing the web page does not help;
• Clearing the browser's cache does not help;
• Closing the tab and reopening it sometimes help;

Additionally, I made some additional troubleshooting.

• This does not relate to the fact that the random order was defined once before. The same was reproduced on a clean 6.4.2 instance;
• Sometimes it will display the slideshow in the correct order, but there's no pattern on this;
• You can clearly see the flag random=false on the URL;
