Icon stays highlighted with all windows closed

[Alexander Browne]

If the last window that was closed is a pinned app, the app's icon stays highlighted on dock. This cosmetic issue occurs if desktop icons are disabled.

In other words,

0. Disable desktop icons (MATE Tweak → Desktop → Show Desktop icons or org.mate.background show-desktop-icons false).
1. Pin at least one app (I'll use MATE Terminal).
2. Open app.
3. Close all other windows.
4. Close app's window.
5. App's icon has no indicator, but it is still highlighted.

I noticed that this will occur with minimized apps open too, so step (3) is more like "close or minimize all other windows".
