Podcast Stops Playing in Background when using Safari

On an iPhone 6 with iOS 8.4.1, a podcast will stop playing on its own when the Podcasts app is running in the background and you do something that transmits data like browse to a website on Safari. This happens even when the podcast is playing back from a file saved on the iPhone. It also only seems to happen if the internet connection is cellular (Verizon LTE in my case). Background playback does not get interrupted when browsing over a wifi connection. I am pretty sure the playback interruption didn't occur with previous versions of iOS but can't be sure. Anyone else see the same thing happen since upgrading to iOS 8.4.1?
