Youtube switches to light mode every once in a while

Every once in awhile youtube switches from dark mode to light mode I am uncertain as to why this happens. This issue is not a very big deal but can lead to minor annoyances.

@NoahHobbs feel free to provide more info about your issue.

Also, is this happens in the same browsing session or after you quit/close and reopen Brave?

Thanks!

It happens when I reopen brave but not consistently.
