Bug summary

Annotations placed outside of an axes withxycoords='figure fraction' are not respected byfig.save_fig(bbox_inches='tight')

Code for reproduction

plt.plot([1,2])figannot=plt.annotate('figure fraction annotation', (0.2,0.97),xycoords='figure fraction')axesannot=plt.annotate('axes fraction annotation', (0.2,1.05),xycoords='axes fraction')plt.gcf().savefig('test.svg',bbox_inches='tight')

Actual outcome

This is a screenshot from Inkscape.

Expected outcome

The annotation using figure fraction should get the same treatment as the annotation using axes fraction.

Additional information

The figure fraction annotation returns aBbox withget_window_extent so it beats me.

The effects of this bug are pretty dramatic if leaving a lot of empty space in a figure window (e.g.add_axes((0.1, 0.5, 0.1, 0.4))).
