Broken id3v2.3 tag after resaving

[unknown321]

Package version: github.com/bogem/id3v2/v2 v2.1.4

Problem:

ID3v2.3 tags are somewhat broken after resaving them without any modifications. In kid3 tags are readable, but album art doesn't render. Completely unreadable on my Walkman NW-A55 (see screenshots).
