Description of the change:

Similar to #123, there is a css rule from the overrides in openshift/console that messes with the layout in the analysis portion of the drawer on the Active Recordings page.

Motivation for the change:

To better align the styling of the console plugin to cryostat web.

Before (Cryostat web vs. Console plugin):

After (Console plugin):

I wonder actually if Patternfly has any design guidelines around this. My sense is that having the empty state and call-to-action at the the top is better because it's closer to the Analyze toolbar button that pulls out the panel, as well as the x that closes it, so this minimizes the amount of cursor movement the user has to do. But visually, maybe having it centered in the panel feels more balanced and pleasing?
