Multichannel files and ChannelSplitter channel layout issue

I’ve just created a simple audio graph with a MediaElementAudioSourceNode connected to ChannelSplitterNode with 6 outputs. The MediaElement's source is a multichannel (5.1) m4a file.
Only the first ChannelSplitterNode’s output is connected to the audio context’s AudioDestinationNode.
I get different behaviors on Chrome and Safari : Chrome plays the front-left channel whereas Safari plays the front-center channel.

Is there anyway to « normalize » the channel splitter behavior ? Or should I create a bug on the WebAudioAPI to block the channel order as it is done for the up/down mixing ?
