Bug report
Using the Qt5Agg backend, applying both bbox_inches='tight' and pad_inches=0 together clips ylabel texts when saving to png format. The same text is not clipped when saving as pdf or with the GTK3Cairo backend.
Code for reproduction
import matplotlib
matplotlib.use('Qt5Agg') ## Causes clipping
#matplotlib.use('GTK3Cairo') ## No clipping
import matplotlib.pyplot as plt
plt.ioff()
plt.plot([1,2,3],[3,1,2])
plt.xlabel('This text is ok. yyggjjpp [] () {}')
plt.ylabel('Top is cut off, for example the fs and brackets. [] () {}')
### Neither PNG nor PDF is clipped with either backend
plt.savefig('test-tight.png',bbox_inches='tight')
plt.savefig('test-tight.pdf',bbox_inches='tight')
### PNG is clipped with Qt5Agg, not GTK3Cairo, pdf is never clipped
plt.savefig('test-tight-nopad.png',bbox_inches='tight',pad_inches=0)
plt.savefig('test-tight-nopad.pdf',bbox_inches='tight',pad_inches=0)Actual outcome
When using backend 'Qt5Agg' in the png output, tall characters in the ylabel are clipped.
Expected outcome
I expect to produce comparable output to the 'GTK3Cairo' backend, which does not clip the labels.
