Latte is using "Plasma::ContainmentView" for docks and panels which derives from "KQuickAddons::QuickViewSharedEngine". Searching the Internet for QQuickView a solutions is to do:

this will reload the source of the view, which is just the tiny qml
file from the shell poackage..
so, you need to actually reload the whole containment i guess.

in order to do that i guess some new api is needed in AppletQuickItem
in libplasmaquick
a reload() method (callable only from c++, not qml) that would do the
same with the internal qmlobject (which is kindof the api of
qquickview, but without a window) to itself and all eventual applet
children (in case it's a containment)
Would you be interested looking into that?
