Night Mode only work for one page and one session in D.Tube

Expected behavior

Login to d.tube and set night mode on, should it be open in another tab or browser, night mode is still active.

Actual behavior

Night mode is one of the most used feature, especially for web video platform. but unfortunately in d.tube, "night mode" disappears when reload page or opening in other browser.
Night mode is more suitable if stored in session or local storage browser, so when refresh or login elsewhere, night mode is still active.
