"Replace activities" placement does not work on GNOME 46

[ondras12345]

Hi,
I have recently updated from Ubuntu 22.04 to 24.04 and noticed the extension stopped working. Through some experimentation, I figured out that it only crashes if I set "Panel Placement" to "Replace activities".

When set to "Replace calendar", there is an error but no crash:

Connection to DBUS window service failed ReferenceError: dateMenu is not defined

"Center, next to calendar" works properly.

"Default" works properly.

"Replace activities" causes a crash:

Connection to DBUS window service failed TypeError: activitiesMenu.get_text is not a function

I'm running f7d9301.
