 When using using audio files on an iOS device with version 9.x the file
 will buffer in its entirety, and then try to play the first half a second
 of the file before resetting the playback position and stopping.

 This does not happen on iOS versions on the 8.x branch or earlier it would

 I've only tested with 4.5-RC and 4.4.2 for now, but both are behaving in
 the same manner.

 Now the question is, is this an iOS bug causing it, or are we doing
 something in wp-mediaelements.js that iOS does not like any more?

 PCs, Macs and Android devices still play the files as expected.

 This comes from tracking https://wordpress.org/support/topic/my-mp3-audio-
 files-get-cut-off-on-mobile-devices-but-work-on-pcs which also includes
 example media URLs that can be used (and are the ones I used in testing)
