I just tried with my 2.2.7 ada7a90f86479e4b61da343f58155a7ba4f17ca4
With AnchorDockingDsgn
Without DockedFormEditor
When I click the designer form it comes to the front as I would expect.
However, if
- I have any Window with just one window in it (i.e. not several ones docked together)
- In docking option have enabled "Floating Windows on top"
then those single Windows will stay on top. And the designer stays behind.
IMHO that should be improved (if not fixed, as it is more like a bug).
If this is the same as your issue, feel free to make an issue report. (and for the time being disable the option)
