Accordion Block - Normal state background color overrides collapsed state

[malalacharm]

Describe the bug
When using a Stackable Accordion block, if the Accordion block background matches the Hovered and Collapsed state colors of the first inner column, the Normal state background color is applied even when the accordion is opened.

To Reproduce
Steps to reproduce the behavior:

1. Add a page
2. Add an Accordion Block
3. On Accordion Block > Style > add a Background color
4. Under Accordion first Inner column > Style > Background color
5. Add a different color for Normal state, set the Hovered and Collapsed state colors to be the same as the Accordion block background.
6. See error (normal state background color applies when accordion is opened)

Expected behavior
When the accordion is opened, the collapsed state background color should be displayed correctly.
