Comment 9 for bug 2008791

Verification done.

The pie chart works as expected now: main color for used space and some light gray for free space. Unfortunately the small squares next to xxx MB/TB used/free are still invisible instead of indicating the color used for each slice. I don't think this is enough to fail validation, since they weren't in the original bug report anyway.

Version tested: 22.04.5 from jammy-proposed
