Enable Backdrops Globally

[Ammer Ashraf Emon]

I love the backdrop feature in Jellyfin. But, is there any way to enable backdrops by default for all users? enableBackdrops:function(){return E} this used to work in v10.9 but after 10.10 this solution no longer works. If anyone knows of any workaround, it would be really helpful.
I really appreciate any help you can provide.

I changed enableBackdrops:function(){return L} to enableBackdrops:function(){return E} and it worked on 10.10.0 (about to update though)

Edit: It works with 10.10.1, it's now change {return R} to {return E} but it works

I was replacing _ With E in my script, so it did not work. Thank you very much.
