Installer doesn't conform to a dark theme

When running the installer from a live session of Ubuntu GNOME I experience the issue shown in the attached screenshot when using a dark theme.

On the panels that show users whether they

1) have enough disk space available,
2) are plugged into a power source (when on a laptop),
3) are connected to the internet,

the background colour seems to be hard coded to white. This doesn't work when the theme is dark, because the text on the panels turns light also in line with the dark theme, rendering it undreadable.

The possible solutions could be

1) hard code the text colour to remain black instead of following the theme, or
2) code the background colour to follow the theme.
