Screen Colour Mode Bug Occur On Steemit-com.

It was today afternoon that I notice there is a bug on steemit.com at the drop-down menu. This bug occurred when I click on "Toggle Night mode". Just like some other people out there, I don't like using the white screen while playing or pressing my mobile phone, has its use to affect me but I was surprised seeing my screen going back to white by itself even without me setting it to do so.
After clicking on the "Toggle Night Mode", it will turn to night mode truly but once I refresh or click on anything else on the phone, the screen will change back to white mode by itself...

Images below expalin better.

here is the white screen mode and the "Toggle Night Mode".

here is the black screen mode after clicking the "Toggle Night mode". And this is how it suppose to be until maybe when I purposely change it to white, BUT in the case is not like that.

Here is the video of how the bug occurred.
