* Bug 1919263 - nbcsports.com videos and photos are not displayed
|
|
*
|
|
* The site loads a script, mparticle.js, using a script tag with async=true,
|
|
* but this can cause it to load too late for other scripts on the page. We
|
|
* can prevent this by changing async to false when they try to load mparticle.js.
