Workspace miniatures on secondary display disappear after clicking on "Show Applications" button

[joaoluizcarvalho]

I am using vertical-overview on Fedora 35 Workstation. I installed it using extensions.gnome.org.

I am using two displays (external monitor as primary display and notebook display as secondary display). On multitasking settings/multi-monitor, I chose "Workspaces on all displays", instead of the default "Workspaces on primary display only".

When I click on the "Activities" button, workspace miniatures are displayed on both displays. However, if I click on the "Show Applications" button, miniatures on the secondary display disappear. Miniatures do not reappear even if I go back the activities overview by click on "Show Applications" again. Miniatures do reappear if I leave activities overview and then return to activities overview, by clicking on "Activites" buttont twice.

This behavier is not observed (workspaces miniatures on secondary display do not disappear) in the default Gnome 41 horizontal overview (i.e., if vertical-overview extension is disabled).
