Connections edit popover does not show from pipelines
Steps to reproduce,
1. Create a connection from Wrangler -> Connections UI
2. Navigate to Pipeline studio and add BigQuery Source to the canvas
3. Click on the Browse button in BQ Source and try to edit the connection there.
After step 3 the connections popover doesn't show up.
This is because of the popover upgrade we did for popper library. This did not happen in the past because the `.fade` styling from popover (or bootstrap) did not have an `opacity` of `0`. The upgrade added the opacity which caused the popover to become invisible.
This should be fixed in 6.5 when we revamp the connections UI.
