nit:
this join will fail if the content does not exist in the
'acceptedExtensions' object and the check in initcomponent
will never trigger
i'd either use the resulting string directly
(".img, .iso"; probably bad because you later compute the regex from
this array) or make an empty array if it does not exists:
const ext = me.acceptedExtensions[me.content] || [];
that way the join will not fail and the initComponent check can
trigger
in reality this will probably not happen so fast, as we do
not often add/modify content types, but would still be nice
to have proper error handling here

nit: you could make that check simpler:
if (!me.acceptedExtensions[me.content])
