[Bug]: (FramelessWebEngineView) and (QWebEngineView) are messing up the (FluentWindow) theme

What happened?

if i added a QWebEngineView or even after using FramelessWebEngineView in FluentWindow class, the whole theme get broken

without the QWebEngineView or FramelessWebEngineView (expected) :

Operation System

Windows 11 Pro, 22H2

Python Version

3.10

PyQt/PySide Version

PyQt5==5.15.9 PyQt5-Qt5==5.15.2

PyQt/PySide-Fluent-Widgets Version

PyQt-Fluent-Widgets==1.4.1 PyQt5-Frameless-Window==0.3.7

How to Reproduce?

As long as you add QWebEngineView to any subpage and display it in various FluentWindow, it will appear. It is normal to display the subpage alone.
