[Manager] Dark Theme: Dropdown option text is invisible (white on white) in Extras manager

[another-brick-in-the-wall]

Description

When the Dark Theme is enabled in the admin panel, unselected/inactive options in the package version dropdown menu are completely invisible. This happens because the text color defaults to white on a white background. The text only becomes visible when hovered over (when the native browser styling applies a blue highlight).

On the Light Theme, everything works as expected.

Environment

• Evolution CMS Version: 3.5.x-dev
• Theme: Dark Theme
• Page Location: manager/#?a=112 (Extras / Package Management)

Steps to Reproduce

1. Enable the Dark Theme in the Evolution CMS manager.
2. Navigate to the Extras/Package Manager page (manager/#?a=112).
3. Click on the version dropdown select box for any multi-version package (e.g., eTinyMCE).
4. Observe the dropdown list items that are not currently hovered by the mouse cursor.

Expected Behavior

The text of all dropdown options should have proper color contrast and be clearly readable (e.g., dark text on a light background, or native dark theme dropdown styling).

Actual Behavior

Inactive dropdown options have white text on a white background, making them invisible unless highlighted.
