I assume this issue does not manifest itself with Qt 5.11?

No, everything works fine with Qt5.11.2
Comment 3 Patrick Silva 2018-10-18 23:47:43 UTC 
Same thing on my Arch running Qt 5.12 beta2.
After the first search, keyboard input stops working.
Comment 4 Kai Uwe Broulik 2018-10-19 06:41:31 UTC 
Does this only affect the application dahshboard or also the other launcher options or krunner?

Yes, only app dashboard, others work correctly.

Had a look with GammaRay:

The scrollview assigns its viewportItem (0,inf) as size.

I suspect this is caused by https://github.com/qt/qtquickcontrols/commit/cb029a36279a1b7d47ec4c58c7916c9b63615b57

Nope, reverting that commit made no difference.
I don't know enough of QML size calculations to debug this further.
