Bug report

Bug summary

TheImageGrid class seems to not behave correctly since the upgrade to matplotlib3.0.0 when theinline backend is used in a Jupyter notebook: the resulting subplots fail to arrange in a grid and are placed on top of eachother. The correct behaviour is reproduced if using thenotebook oripympl backends. Thanks!

Code for reproduction
