Bug Description

Ubuntu release:

Ubuntu Bionic Beaver (development branch), but the problem also occurs in Kubuntu 17.10 if upgraded to Plasma 5.12 through the backports PPA.

Package version:

  Installed: 4:5.12.4-0ubuntu1
  Candidate: 4:5.12.4-0ubuntu1
  Version table:
 *** 4:5.12.4-0ubuntu1 500
        500 http://de.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
        100 /var/lib/dpkg/status

What I expect to happen:

Application categories with more applications than will fit on one page naturally get a scrollbar. I expect this scrollbar to turn blue/display some other "hover decoration" when moused over and to respond to clicking and dragging.

What happens instead:

Nothing. Clicking the scrollbar in (say) my rather large Games category has the same effect as clicking on an empty space in the Application Dashboard widget; i.e., it just exits the widget.

Please note: the scrollbar in the All Applications page DOES work; it's only the scrollbars for the regular categories (as specified in a .menu) file that do not.

Also, scrolling with the mouse wheel still works, and the scrollbars (while unresponsive to clicking) will move correctly when doing so.

I wish I had any logs to provide but I don't know where this would be logged, if anywhere.

It still works on my Kubuntu 17.10 install with Plasma 5.10.

Using Xorg.
