Power Table Header background color

After the upgrade from 8.1.5 to 8.1.10 it was noted that for the power table the header background color behavior has changed now it takes the same color as the background color set on the power table ( instead of the default light_gray), we did try to use formatHeaderStyle function which managed to change the background color but created other issues (missing borders between columns and when hovering on filterable column).
Also, another issue was noted for the disabled behavior for buttons, the new overlay color is white which will make the white foreground text on a button unreadable.

Is it possible to revert back to the previous settings?
