Zoom WEB SDK Panelist / Host join meeting role / email detection

The only way I can get it to work is if I promote a user to a panelist from within a meeting. Then when that user leaves and re-joins, they maintain their panelist status.

@tommy This is exactly the same problem I encountered with web SDK 1.8.0. Reproduce steps:

1. Add a webinar panelist on zoom dashboard
2. Pass panelist email as userEmail and role=0 on joining the meeting in SDK
3. The panelist can only have the view-only attendee view, not the panelist view.
