Theme color changes to 'automatic' when changing background image

When manually selecting a theme color in the settings and then changing the wallpaper, the theme color is changed back to ‘automatic’.

Unfortunately this also happens with changing the wallpaper via a routine/mode, i.e. I have a mode called ‘sleep’ that activates every night at a certain time and this mode changes the wallpaper to a darker wallpaper. So it also triggers the bug leaving the Niagara button in an undesired color.

Steps to reproduce:

1. Go the Niagara settings

2. Go to theme / theme color

3. Select a manual color from the background or standard section

4. Notice that the Niagara button shows this color

5. Change the wallpaper

6. Notice that the color of the Niagara button did change

7. In Niagara settings / theme / theme color the option switched to ‘automatic’

8. I would prefer that Niagara keeps the manually selected color although it might not fit the new wallpaper that I have over the night
