Issue Summary

This is reproducible on Data Center: (yes)

After upgrading from Jira 9.12.6 to 9.15.2 the colors of the navigation links changed unexpectedly.

We found that changing the color of the "Drop-down menu item - text colour" in the Look and Feel menu now changes the color of other unwanted texts.

While this is not a major issue, the actual color of the drop-down menus is affected, breaking our original style on the Look and Feel configurations.

Steps to Reproduce

1. Change the "Drop-down menu item - text colour" to white.

Expected Results

The "Drop-down menu item - text colour" only affects drop-down menu items.

Actual Results

The sidebar navigation links for all Jira are "missing" on the default color scheme.

Jira 9.12.6          >          9.15.2

Investigation

I modified the color to a unique color code and used this unique "#ffffaa" to search the UI HTML to find where this was being changed, then I found a code pertaining to light/dark themes in the 9.15.2 version:

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available
