Bug report

Bug summary

I noticed this in the mathtext tutorial after#20605. The text in the accent section is cut off, so that the triple dot and quadruple dot accent appear to be the same.

Code for reproduction

frommatplotlib.font_managerimportFontPropertiesfrommatplotlib.mathtextimportmath_to_imagepstra= [r'$\dot{x}$',r'$\ddot{x}$',r'$\dddot{x}$',r'$\ddddot{x}$']fori,textinenumerate(pstra):math_to_image(text,f'text{i}.png',prop=FontProperties(size=50),dpi=100)

Actual outcome

In fact, looking at it closely, I think thex may be cut off in the top right as well. It should come to a point, I believe, not a corner.

Expected outcome

The last image should have 4 dots above the x.
