I was able to reproduce this with konsole built from git master:

qt.qpa.wayland: setGrabPopup called with a parent,
QtWaylandClient::QWaylandXdgSurface(0x555555c37360) which does not match the
current topmost grabbing popup,
QtWaylandClient::QWaylandXdgSurface(0x555556289160) According to the xdg-shell
protocol, this is not allowed. The wayland QPA plugin is currently handling it
by setting the parent to the topmost grabbing popup. Note, however, that this
may cause positioning errors and popups closing unxpectedly because xdg-shell
mandate that child popups close before parents
