Bug summary

r"$\|$" should render as a double vertical bar, which it does with usetex or with math_fontfamily="cm", but not with the default "dejavusans" math_fontfamily.

Code for reproduction

s = r"single$|$ double$\|$"
figtext(.5, .7, s); figtext(.5, .6, s, math_fontfamily="cm"); figtext(.5, .5, s, usetex=True)

Actual outcome

Expected outcome

Double vertical bar in the first line too.
