Kickoff applet - right click on URL breaks hover

SUMMARY
Right clicking on search results that represent some URL (including "Get %appname%…" entries that launch Discover) breaks hovering of list items for both search results view and the starting page (Applications view) on the right.

STEPS TO REPRODUCE
1. Open Application Launcher (Kickoff).
2. Search for some URL you've been visiting or have a tab open.
3. Right click on it.

OBSERVED RESULT

No context menu would open, but hover states are now broken (items won't highlight in the list and other side-effects).
And the console output is:

Opening menu at 304 31

Shouldn't break like that.
