What does ZoomMtg.init isLockBottom do?

Meeting SDK Type and Version
Web 3.1.0

Description
What is the purpose of the ZoomMtg.init isLockBottom parameter. In my testing I can’t see any difference when this is set to true or false.

@tommy Wondering if you could help clarify this? Since 3.1.0 it seems isLockBottom no longer has any effect?

Bumping to try to get this resolved…

I just tested this again using the latest version 3.1.6 and I still can’t see isLockBottom making any difference on any device?
