In the community portals, the Report Summary lightning component is a fixed size (and a small size at that). Any report longer than that fixed size prevents us from seeing more records at once and is tedious to scroll through.

Dashboard components had this issue previously as well, and that was resolved in 2018. Up until it was fixed, there was a workaround to override the height (view link)

I just want to know what class I need to modify to so that I can display the report at full height. Unable to find it through Inspect Element
