Backslashes being added in latest version also (4.2.8)

I can reproduce the mentioned behaviour, it breaks GA functionality and renders it useless here. We re-pasted a clean version of the code into the input field and are going to stay the hell away from there now.

I’m not sure, but plugin updates might possibly cause more backslashes in addition to saving the settings.

I’ve also reproduced this behaviour and the solutions for now is to save the custom code and re-paste it every time we need to update the plugin.
