How can I stop mutagen automatically updating the ID3 version?

Question

When I tried to embed album art in an MP3, mutagen updated the ID3 tag to version 2.4 - which I don't want, because in ID3v2.4 my cell phone (which runs Windows Phone 8) and my computer can't recognize the tags.

Apparently, simply changing the mutagen.id3.version attribute doesn't work: the real version doesn't change.

There is a "v2_version" option in tags saving function, shown below.

import mutagen
audio=mutagen.File('1.mp3')
#audio.tags.update_to_v23()
audio.tags.save(v2_version=3)

It is also documented in help()

help(audio.tags.save)

as below:

save(self, filename=None, v1=1, v2_version=4, v23_sep='/')
