1.7.7 joins meeting but then fails without errors

Description
The WebSDK (1.7.7) is able to join, but then shows the infamous “Your connection has timed out” dialog. But I see no errors in the console, and it appears to connect to the WebSocket without issue.

Error
Same as description

Which version?
WebSDK 1.7.7
Chrome (desktop, latest)
Pro Zoom account
Normal meeting (not Webinar)
