New description:
When trying to map and copy time_id3 metadata from a .ts file to a .ts
file, the time_id3 metadata is copied (e.g PRIV tags) but the ID3 header
is not inserted (0x49 0x44 0x33).

as follows:
ID3v2/file identifier "ID3"
ID3v2 version $04 00
ID3v2 flags %abcd0000
ID3v2 size 4 * %0xxxxxxx
https://id3.org/id3v2.4.0-structure
{{{

-f mpegts 3b.ts
