Bug summary

Ladies and Gentlemen,
Zoom und pan is not working after writing pdf pages.
Within matplotlib version 3.7.5 it is working.
In e.g. 3.8.3 it does not react any more.

Code for reproduction

import matplotlib.pyplot as plt
from matplotlib.backends.backend_pdf import PdfPages
fig, ax = plt.subplots()
ax.plot([1, 2, 3], [4, 5, 6])
filename = "test4.pdf"
with PdfPages(filename) as pdf:
    fig.show()
    pdf.savefig() # <== if you comment this line, then zoom is working fine. However it is not getting stored.

Actual outcome

Expected outcome

Additional information

In earlier versions it has been working fine.
It is also not working within jupyterlab.
It was testet in Spyder IDE 5.5.1 and IDLE(Python 3.12 64-bit)
I take the earlier matplotlib version instead.
