When Bluetooth is enabled youtube/spotify/soundcloud stops working

Since last week I had a really strange issue. Please note that before everything worked fine.

When I connect/enable my Bluetooth headphones everything HTML5 enabled like Spotify Soundcloud Youtube stops working. When I disable/disconnect the Bluetooth headphone it starts playing immediately.

i disabled the mic input and the mode was set to HSP and switched that back to A2DP and my videos immediately started to play again

In Sound Settings, Output, select the Headset (bluetooth accessory) in the table on the left and change the mode to "Headset Head Unit (HSP/HFP)" and then change it to "High Fidelity Playback (A2DP Sink)" (even if it was already in this mode).

If bluetooth fails to pair when you fiddle with it, turn the bluetooth off and on in Bluetooth Settings.
