Detailed Memory Information - Not Honoring System Font-Sizes

If you right-click on a process in ksysguard, and click then "Detailed Memory Information", the window that pops up contains text that doesn't honor the font-size preferences set via KDE's system settings utility.

This accessibility issue is especially pronounced on 4K monitors.
