Bug report: QTitanRibbon assert failure with unexpected WindowFrameSection

Bug report: QTitanRibbon assert failure with unexpected WindowFrameSection was created by 无锡飞谱电子信息技术有限公司
In QTitanRibbon 5.1.0, the following function:
int QTITAN_PREPEND_NAMESPACE(qtn_get_sys_command_win)(QWidget* window, QMouseEvent* event,
Qt::WindowFrameSection frameSection):


in my case, the frameSection sometimes is assigned as Qt::NoSection, and so it will lead to the assert failure in the following line:
case Qt::TitleBarArea:
if (event->type() == QEvent::MouseButtonDblClick)
{
if (event->button() == Qt::LeftButton)
{
if (window->isMaximized())
command = SC_RESTORE;
else
command = SC_MAXIMIZE;
}
}
else
command = SC_MOVE | 0x0002;

break;
default:
Q_ASSERT(false);
break;
}
return command;


I doubted whether this assertion failure is expected?

Strangely enough, this error was fixed in 5.1. How did you reproduce it? Could you describe your actions?

Sometimes, this error happened when my GUI application starts up without maximization. I can copy the calling stack to you once this error happened.

Today I switched to QTitanRibbon 5.1 with Qt 5.12.5 VS64 2017 and althou have an issue with an assert.
I removed the Windows Title bar:

ribbonBar()->setFrameThemeEnabled();

If I then close the application i get the following assert as in the attached screenshot.

File QtnPlatform_win.cpp
line: 398
instruction: Q_ASSERT(m_hookHash.size() == 0);

I commented it out, no I can close my application without an assert.
Is this line realy necessary?

Regards
Michael
