Bug summary

For some figure/subplot/colorbar axis aspect ratios, the colorbar is outside of its axes when saved into vectorial formats (pdf, svg).

Code for reproduction

importnumpyasnpimportmatplotlib.pyplotaspltx=np.linspace(0,100,100)y=np.linspace(0,100,100)z=x[None, :]**2+y[:,None]**2fig,axarr=plt.subplots(1,2,figsize=(3,2.8789385625),constrained_layout=True,sharey=True)ax=axarr[0]a=ax.pcolormesh(x,y,z,snap=True)fig.colorbar(a,ax=ax,location='top')#ax=axarr[1]a=ax.pcolormesh(x,y,z,snap=True)fig.colorbar(a,ax=ax,location='top')plt.savefig('test_colorbar.pdf')plt.savefig('test_colorbar.svg')plt.savefig('test_colorbar.png',dpi=800)

Actual outcome

Expected outcome

The colorbar should be within its axis, and not shifted upward.

Additional information

• It does not occur when the figure is saved to non-vectorial format (i.e png, etc ..)
• In this case, it does not occur for all figure aspect ratios.
• It was already the case in matplotlib 3.4.3
