Sorry to revive this thread. I would have always agreed with the above. But, I'm running KDE Plasma (Kubuntu) for the first time and It seems to integrate somehow with Chrome's file chooser. Here's a screenshot:

Plasma has browser integration and that's why you see that. Try this, press Alt+Space or F2 and start typing, you'll see krunner listing matches for your query and among those your browser bookmarks as well.
