Color Picker window closes when selecting objects in the viewport with the Eye Dropper Tool

The color picker window stays open if the Eye Dropper tool selects color from anywhere other than the viewport. The color is captured in the color picker before it closes, but makes it a nightmare to open back up if a user picked the wrong color.

The color picker closes because when selecting a color in the viewport, it selects the object and therefore changes the detail panel to the selected object. Because the color picker was opened from the details panel it closes.

A possible fix could be disabling the ability to select anything in the editor while the color picker is active

This happens in 4.15.1 so this is not a regression

1. Open any project
2. Select Light Source in the World Outliner
3. In the Details Panel > Light Shafts > Bloom Tint select the color bar
4. Select the Eye Dropper Tool and click somewhere in the Viewport

Result: New color is set but the Color Picker window closes

Expected Results: New color is set and the Color Picker window stays open.
