GtkFrame: A hidden label widget confuses the size allocation (regression in GTK+ 3)

Created attachment 200158 [details] test_frame_label.c This test case shows that the GtkFrame's whole size allocation is incorrect, causing truncation of widgets, if the label widget is not visible. I noticed this in Glom, though I've worked around it by removing the label instead of just hide()ing it. This is not a problem in GTK+ 2.
Created attachment 200159 [details] screenshot_test_frame_label.png A screenshot of the window created by this test case.
This works both in 3.18 and master here.
assuming it is fixed then
