What steps will reproduce the problem?
1. Cast a tab to a meeting via the three-dot menu -> Cast...

What is the expected result?

Tab casting is stable.

What happens instead of that?

Tab casting stops after several minutes.

Please provide any additional information below. Attach a screenshot if
possible.

Because tab casting stops, I kept re-casting the same tab,
which resulted in multiple icons of myself as shown in the screenshot.
