on .ui load a GtkCheckBox label alignment in WYSIWYG view appears centered
In glade 3.38.2 if I load a GtkCheckButton with no child-alignments set then its label appears centred in the WYSIWYG view demo.ui but it is really rendered by gtk left-aligned. If I add a new one, then it appears left-aligned initially as expected, but will appear centred on save and reload.
