Mojave backslash keybinding

I upgraded my computer to OSX Mojave a while back. Most things work really well, but I have faced some strange keybinding issues with my Swedish keyboard. One such thing is backslash, which now opens up the help menu instead.

To restore the pre-Mojave behavior, open Keyboard Settings in System Preferences, then select the Shortcuts tab, select Application shortcuts in the vertical menu, then uncheck Show help menu:

Keyboard Settings

After this, the standard Swedish backslash keybinding should work once again.
