FeatureTable checkboxes are now dark

[KenBuja]

Why are the checkboxes in the FeatureTable now dark? This changed as of ver 4.19. I only noticed this when I updated my code from 4.17.

The figures in the documentation show light gray boxes, but in the sample they are dark gray. I've tracked it down to the .esri-grid --lumo-contrast-20pct, which also affects the border of the table. Can you separate these out so the border is dark and the checkboxes are light again? The new checkboxes are less visually appealing.
