The Steemit front-end should be able to save the visual preferences into local storage for later use. When you toggle the night mode and you refresh the page, this preference is lost. You need to toggle it again if you want to enable the night mode.
Expected behavior
The Steemit front-end should save the day light or night light preference for later user. For instance, if you toggle the night mode and refresh the page, it should stay in night mode.
Steps to reproduce
Open Steemit website
Click into your profile picture (supposing you are logged in)
Click on Toggle Night Mode (your page will turn into a dark theme)
Refresh the page (White theme is back)
