qt.accessibility.core throws errors from child items created in disabled state

I was refactoring my user interface to make use of lazy loading a bit more.
As it was being build I wanted to make sure the interface does not yet receive user inputs.
Thus I was calling:

self.setEnabled(False)

then built all the actions, lists, fill it with list items, widgets, tabs and so on until I finally:

self.setEnabled(True)

the whole thing again. Worked nice in 5.13.x I think. But from 5.14.0 on there were these errors coming:

qt.accessibility.core: Cannot create accessible child interface for object: QTabBar(0x24f514fea20, name = "qt_tabwidget_tabbar") index: 2

Mostly in chunks of 3 lines.

Seems when I just create the container widgets outside of the disabled state everything is fine again.

Parent widgets that I experienced this with:

• QMenuBar - first is OK, from when hovering the second menu: 3 lines of errors, 3 more on click
• QListWidget - first 3 list items are OK, from clicking the fourth 3 lines of errors then 3 more when changing away from the list item
• QTabBar - first 2 tab widgets are OK, from clicking the third 2 lines or errors ...

might be there is more. I put a code example for the QmenuBar into the Attachments

Steps to reproduce:

• (Windows) Ensure an accessibility tool or other UI Automation client, like Microsoft Narrator or Inspect is running
• Run example
