krunner getting keystrokes

SUMMARY
When the Application Launcher widget is embedded in a large panel - large enough where the applet switches from the icon view to the full content - the search field does not accept keyboard input.

STEPS TO REPRODUCE
1. Create an auto-hide panel at the bottom of the screen to host the application launcher widget
1a. Add an empty panel to the bottom edge of the screen
1b. Set new panel to auto hide
1c. Set panel to center alignment.
1d. Increase panel height to ~>560px.
1e. Adjust panel width to roughly the same as the height
1f. Close out of edit mode.
2. Hover the mouse cursor at the bottom of the screen to show the panel, select the search field and attempt to type. 


OBSERVED RESULT
The application launcher search field does not show what is being typed. If there was an app which previously had a focused search field, it appears to be getting the typed characters. For example, if no other applications are running/visible, krunner will trigger and show the search results. If firefox was open with the duckduckgo search field focused before, it would get the typed characters in that field.

EXPECTED RESULT
Application Launcher search field shows what is being typed and shows search results.
