Export Asset using Bounding Box
I think it should be possible to export our assets using the bounding box either clip mask or a group of objects
I do a work around, where I create a circle or rectangle that has no fill or stroke and select all and drag in. But it's buggy - WILL work if you immediately export that file. If you do another stack of items and then try to export both - ONLY the latest one will work proper, and the previous one will be in the upper left corner with a big area of emptiness.
This is on a lot of different files, both win and mac, and tested across multiple computers.
BUT, at least if you're uber patient and do it one by one, it works. What the HECK is going on with Export Assets, Illustrator team!??
