While running `MP4Box -diso ...` xml dump on files in the ISOBMFF conformance suite, I noticed that MP4Box has issues with some of the files:

1. Two files produce invalid xml files ([09_text.mp4](https://conformance.mpeg.expert/ISOBMFF/published/isobmff/09_text.mp4), [22_tx3g.mp4](https://conformance.mpeg.expert/ISOBMFF/published/isobmff/22_tx3g.mp4))
The issue seems to come from the dump of the `DefaultBox` where the closing xml tag is missing. 
It looks like `gf_isom_box_dump_done` call is missing  in https://github.com/gpac/gpac/blob/54bce6b07332fabb016cf9a4ae9b80aa33bca3cd/src/isomedia/box_dump.c#L1929

2. Three files can not be opened at all.
