Bug report

Bug summary

A trailing space after a mathtext block (but outside of the mathtext) and a traling space after a normal text block affect horizontalialignment differently.

Code for reproduction

from pylab import *
rcdefaults()
gca().set_axis_off()
axvline(0, lw=1)
text(0, .95, "$1.0$ ", ha="right")
text(0, .9, "$1.0$", ha="right")
text(0, .85, "1.0 ", ha="right")
text(0, .8, "1.0", ha="right")
text(.1, .95, "$1.0$ |", ha="right")
text(.1, .9, "$1.0$|", ha="right")
text(.1, .85, "1.0 |", ha="right")
text(.1, .8, "1.0|", ha="right")
text(.2, .95, "mathtext + space")
text(.2, .9, "mathtext - space")
text(.2, .85, "text + space")
text(.2, .8, "text - space")
show()

Actual outcome

It is reasonable to have slightly different sizes for a space after a "0" in mathtext and a "0" in normal text. As the 1.0 |s show, the difference, if any, is minor (i.e. the space has more or less the same size). However, the horizontal alignment of $1.0$ and 1.0 with ha="right" are clearly quite different, with the space added in the mathtext case much smaller.

Expected outcome

More consistent behavior?
