Comment:

 I came across this problem today, wondering why my plugin didn't work as
 usual. A workaround I found was to just turn it on everywhere on init, but
 it would be nice to turn it on for a particular plugin's CPT.

 My patch is simple - if it's already set and an array, merge the arrays.
 If it's already set to true (thumbnails everywhere), keep it true. Tested
 it on multiple CPTs and hooks.
