Description:
When using COSMIC alpha and Libreoffice writer with the default system theme (light theme), the Icons appear white-on-white background, so one can't recognise them.
Switching to dark theme makes the Icons be white-on-dark so one can recognise them again.

I shall test it later in KDE plasma wayland too.

Steps to Reproduce:
1.Have COSMIC installed.
1.a. On arch linux one can install COSMIC from the extra repos:  https://archlinux.org/packages/?name=cosmic-session

2.Change default system theme of COSMIC to light :
2.a. Open COSMIC settings
2.b. Navigate: `Desktop` → `Appearance` → `Colors and light & dark mode`
2.c. set it to Light 
3. Open Libreoffice writer


Actual Results:
The icons in the opper portion of the UI are White on white background, so you cant read them

Expected Results:
The icons in grey or any other color then white, for better contrast


Reproducible: Always
