"lost" our aspera secondary button box

it would appear, perhaps, that the styling on webui 3.0.0 has caught up with our aspera styling, and is overriding our secondary class. It would seem we didn't add this secondary class until the most recent 3.0.0 release of webui. https://jira.nuxeo.com/browse/ELEMENTS-1152.

Now, for aspera, we have lost some of our styling that we used on the connector. (see screenshots).

Steps for reproducing...On PR 177 preview (when available, noticed on the below screens):

• On the dashboard/transfer view, "+ new upload" the styling is gone
• on the dashboard/transfer view, click "new upload", on auto create modal, "no" button
• on the dashboard/transfer view, click to share the transfer: on "add" button and "done" button
• on dashboard/transfer view, click to complete transfer, "no" button styling is gone.
• on the transfer view, with files in the transfer, click to edit metadata in bulk, "cancel" button styling is gone
