Top Bar Gradient for Folder containing Image doesn't change with Theme.

[benpinpop]

Describe the bug

Whenever an image is attached to a folder within a course, the top bar contains a gradient, allowing you to click see more (to display the image). This gradient/color does not change to match the theme when the theme is changed within Schoology Plus Settings.

Steps to reproduce

Install Schoology Plus.
Access the Folder within your course that has a photo attached to it.
Change your color theme to something other than the default.

Expected behavior

The gradient should match the color theme.
