Center-aligned title's font size doesn't increase.

Summary

The title's font size doesn't increase at some point when it is center-aligned.
This behavior may be correct for aligning an ABC label, but I'll report it because it differs from what the user expects.

Reproducer

When I set the title to be center-aligned,

fig, ax = uplt.subplots()
ax.format(
 abc=True,
 ctitle="title longlonglonglonglonglonglonglong", # it is same as "title=..."
 fontsize=20,
)

When I set the title to be left-aligned,

fig, ax = uplt.subplots()
ax.format(
 abc=True,
 ltitle="title longlonglonglonglonglonglonglong",
 fontsize=20,
)

This should be an easy fix. I think I shoul put some wiring in place to do a relative scaling for the entire plot as sometimes the scaling of the title looks awkward in comparison.
