SOLVED: Possible Bug: Some user settings will reset to default after clearing browser cache

[JANONYMOUS]

I noticed that clearing the browser cache (Safari in my case) will reset some custom settings.

So far I have noticed the following:

• Settings > Display > Theme [resets to Dark]
  
• Settings > Libraries > Library page size [resets to 100]
  

Note that this doesn't affect every custom setting.  For example, the dashboard theme setting does not revert to the dark theme.
