Bug summary

In the reference figure https://github.com/matplotlib/matplotlib/blob/main/lib/matplotlib/tests/baseline_images/test_mathtext/mathtext_dejavuserif_00.pdf

the dot above the s is differently positioned. Not clear why as the expressions are \dot s and \dot{s} respectively. This doesn't happen to all fonts (maybe only this?).

It also happens in the svg image, although not as clear. Looking at the source, the x-position difference between the accent and character is 54.4 for the left and 57.5 for the right.

Code for reproduction

import matplotlib.pyplot
plt.text(0.5, 0.5, r'$\dot s + \dot{s}$')
plt.savefig('sdot.pdf')
plt.savefig('sdot.svg')

Actual outcome

Different rendering

Expected outcome

Identical rendering
