After clearing localstorage, theme always defaults to dark

[djmtype]

For some reason the dark mode remains even after local storage is cleared.

Here are the steps I tried to reproduce.

1. Set my OS theme to light
2. Cleared my browser's local storage
3. Visited the page again, and pressed enter on the keyboard
4. Also tried refreshing the browser page

It seems the _x_darkMode still remains as true. If the local storage is empty, it should inherit the operating system's settings, correct?

I tested on Chrome and Firefox.
