    Description

      When I hover over a symbol in Kate, the tooltip is provided by the LSP. When I use the mouse button to double click the text and select it, Kate crashes. This is not exactly consistently reproducible but the common theme is to create a popup and then click on the popup or outside rapidly.

      I also see the following warning in the journal. However, this is only printed for some crashes, not all.

      Sep 12 22:45:36 xx kate[27621]: qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x5587c084037
      0) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x5587c069b810) 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 p
      arents
