Minor issues(?) with padding color settings

Put the question mark cause I’m not sure these should be considered issues. Demonstrated both in this video and described below:

1) Using the No fill (transparent) option in Colour tab seems to make it use the color set in Gradient

2) If you set an image background, then switch to some other tab, it switches to that tab’s background setting accordingly. But switching back to the Image tab doesn’t switch back to the image background.
