ofxPanel.setup("title") doesn't display panel title

As the title says, ofxPanel.setup(“title”) doesn’t display panel title.
According to this issue it should’ve been fixed.

I am using the same test code as in the issue: examples/gui/guiExample/ofApp.cpp, line 11:

gui.setup("test"); // most of the time you don't need a name
gui.setup(); // most of the time you don't need a name

I tested in v0.9.8 on Windows with Visual Studio 2017.
