I'm building a PySide panel using QtWebEngineWidgets and I'm experiencing a strange bug where the UI works fine when loaded, but when you click another pane in the UI and try to go back, the panel is now frozen and only updates after you resize it.

You can replicate with the sample panel:

1. Go to “New Pane Tab” > “Python Panel”
2. Select the “Quick Start: Calendar Example” tab
3. Click and scroll the page
4. Click away at another pane
5. Try to click back and scroll the Python Panel
6. Notice you can't click or scroll on the page till resizing the UI

I've confirmed this bug in our studio's version of Houdini 17.5.229 and the latest 17.5.391.

If anyone has any workarounds for this that would be amazing, thanks!
