Indistinguishable checkboxes at the eval when dark mode is enabled

[marapper]

Switch to Eval tab -> open any evalset to see the list of test cases.

--chat-side-drawer-color is applied to tbody and overriden by the color of tr.mat-mdc-header-row which set it to black (var(--mat-table-header-headline-color, var(--mat-sys-on-surface, rgba(0, 0, 0, 0.87))), no rule for dark mode?), and .mat-mdc-row (var(--mat-table-row-item-label-text-color, var(--mat-sys-on-surface, rgba(0, 0, 0, 0.87))))

And the same but inversded moment with light mode and breadcrumbs

mat-icon is white

• var(--mat-icon-color, inherit) is undefined
• • inline style, explicitly set it to white
