video preview shows before all meetings except my own

I am on Zoom 5.17.11 on Mac Sonoma 14.4.1.

I have video previews enabled (Settings -> Video -> Always show video preview dialog when joining).

I get the expected video preview when joining others' meetings.  But when I start *my own meetings*, I get no preview and am launched straight into the room with video on.

How do I get video preview before starting my own meetings?
