Comment 9 for bug 1688687

Testing in Zesty. It's done after testing the fix for bug 1680604, so the packages are already updated to version 1.18.1-0ubuntu2.1 from zesty-proposed.

- launched Caja
- changed to /usr/lib/x86_64-linux-gnu/mate-notification-daemon/engines/
- reduced the window's width so that some pathbar buttons would be hidden
- used mousewheel scroll over all pathbar buttons
- used mousewheel scroll over left/right arrow buttons on the sides of the pathbar
- clicked on arrow buttons as well - they do the same as mousewheel scrolling
- also checked that all pathbar buttons work properly (they do)

The scrolling works. It does the same as the arrow buttons on the sides of the pathbar.
Scrolling down or clicking on right arrow reveals hidden buttons at the end of the pathbar.
Scrolling up or clicking on left arrow does the same at the start of the pathbar.
