This avoids numerous crashes when using the keyboard navigation in Discover during searches. It would seem that, without this, we occasionally (which during a search with auto-updating results means regularly) send key events to a component which is not yet ready to receive them... It would be nice if this were caught by Qt, but i guess that might be a little expensive to do generically.
nb: i would like this to be a typesafe comparison, but... yay qml ;)
