gtk_main_get_window_group function return different results for
gtk_grab_add and gtk_grab_remove, but widget address was same in both
functions:
if (GTK_IS_WINDOW (toplevel))
return gtk_window_get_group (GTK_WINDOW (toplevel));
else
return gtk_window_get_group (NULL);
On gtk_grab_add window group is 0x555555b0b160 for widget 0x555555e50780:

Parent of the widget was changed by gtk_tree_view_multipress_gesture_pressed ->
.. -> gtk_cell_area_activate_cell -> gtk_cell_area_add_editable -> ..signal..
-> gtk_tree_view_column_add_editable_callback -> _gtk_tree_view_add_editable ->
gtk_tree_view_put -> gtk_widget_set_parent
So, gtk_cell_area_activate_cell of gtk+3 (3.22.7) has incorrect order of
actions which broke gtk_grab_add / gtk_grab_remove pair
