Describe the bug

If we have a dark "Theme" but a light "editor color scheme", the preview of generated tests mixed up both. The background color follows the "Theme" setting and the text the "editor color scheme" setting. So we have a dark background with a dark text.

The bug also exists with a light "Theme", and a dark "editor color scheme"

To Reproduce

Steps to reproduce the behavior:

1. Go to Settings -> Appearance
2. Select a dark "Theme" and a light "editor color scheme" (like in the screenshot below)
3. Generate a test with TestSpark
4. In the TestSpark panel, the generated tests preview does not respect "editor color scheme" for the background color.

Expected behavior

The background color of the generated test preview must follow "editor color scheme" and not "Theme"
