The default color scheme of the editor of GNU Octave's GUI, for some reason,
depends on whether the system is using light or dark mode.
If the system is using light mode, then the default color scheme will be
correct: either white background with dark text, or dark background with light
text.
If, however, the system is using dark mode, then some elements of the default
color scheme will be switched, but not others: that means you'll get a white
background with light text, or a dark background with dark text.

=== Steps To Reproduce ===
Steps to reproduce the behavior:
* Put your desktop environment in dark mode (I used KDE Plasma (both X11 and
Wayland) with Breeze Dark)
* Open Octave's GUI
* If it's not the first time opening Octave, reload the default style:
        * In the top bar, Edit > Preferences
        * Click on Editor, scroll down to the almost bottom, and click "Reload
default styles"
        * Apply
* In the main window, go to the Editor
* When writing text, you'll see that it's dark with a dark background.
        * If you checked "Second color mode (light/dark)" (and "Reload default
styles") in the settings, then it's light with a white background.

=== Expected behavior ===
The system theme should either change the color style completely or not at
all, instead of changing it partially and creating a poor contrast. 

=== Additional context ===
This only affects loading the default color scheme: when already applied,
changing the system theme changes nothing in Octave.
A workaround to this issue is thus setting the system theme to light, applying
the desired color scheme in Octave, and then switching back to the system dark
theme.
