PR summary

Fixes #30770. The problem was that set_title restores default styles, so we should only update the string.

No test added per #30770 (comment), but I have run the example code against my branch and verified I can change the title in the gui without its style reverting.

Note that title is initialised as an empty Text object so set_text will work regardless of whether the user previously added a title.

matplotlib/lib/matplotlib/axes/_base.py

Lines 1369 to 1374 in 0a9f2d5

self.title = mtext.Text(
x=0.5, y=y, text='',
fontproperties=props,
verticalalignment='baseline',
horizontalalignment='center',
)
