Describe the bug

If a user tries to use the picker to select a hue/saturation/brightness on the screen from the color equalizer module in the quick access panel, nothing shows up in the module. The same picker used in the full module works fine and shows a vertical line where the color is.

Steps to reproduce

1. Open an image, select the color equalizer section of the quick access panel, and click on the picker
2. select a spot on the image

a marker appears on the image, but no vertical shows up in the module itself:

If the full module is opened, then the vertical line shows up:

Expected behavior

A vertical line should be shown in the color equalizer module for the select spot on the image
