Qt Designer : Edit Tab Order is lost when moving a QtWidget into a QGridLayout

I have a QGridLayout with several widgets in it
and configured the Tab Order with the good order

If I move widget from one place to another one on the grid, the Tab Order is lost, and the moved widget revert to the default tab order, the other ones keep the Tab Order

I think all the widgets must keep the same TabOrder when you move them

The problem doesn't occur when there is no QGridLayout

before : three QPushButton, tab order is correct
after : the QPushButton 2 and 3 have been swaped, the tab order is incorrect, and do not follow the moved widgets
