thmb item reference in track reference section

[bradh]

In 8.3.3.3, on track references, it says

'thmb':
— this track contains thumbnail images for the referenced track. A thumbnail track shall not be linked to another thumbnail track with the 'thmb' item reference.

I think that should be "...with the thmb track reference" (not item reference - which looks like a copy-n-paste from HEIF).

Thanks, the comment is valid.
The draft 8th Edition text fixes this as follows:

'thmb' this track contains thumbnail images for the referenced track. A thumbnail track shall not be linked to another thumbnail track with the 'thmb' track reference.
