Description:
I have Libreoffice 7.0 (Opensuse Tumbleweed). When I use the Breeze theme, Writer shows the fonts preview without problems (in the drop-down menu, white background and black fonts). But when I use the dark theme, the drop-down menu fails and looks almost illegible.

Steps to Reproduce:
1. Apply Breeze dark theme (Opensuse Tumbleweed)
2. Check fonts preview (in Writer)
3. Drop-down fonts menu looks illegible (-very- light grey fonts with white background).
4. The normal Breeze theme (light) works with any problems (in Writer).

Actual Results:
When I apply de dark Breeze theme the drop-down fonts menu fails: white fonts (in fact, light grey) with white background. When I disable de fonts preview the drop-down menu looks normal (black background with white fonts, obviously without preview).

Expected Results:
The drop-down fonts menu (in dark mode, with fonts preview checked in Writer) should be legible, (dark background with white fonts).


Reproducible: Always


User Profile Reset: Yes



Additional Info:
The fonts size menu or paragraph works properly with dark theme. The problem is only in the fonts menu with preview activated.
