Graphic style with rotated pattern not saved in Library

Hi @dtpetermaas,

Thanks for the detailed follow-up and for sharing the recording. I tested this thoroughly on my end and I can now reproduce the behavior as described. When the object has a single fill with a rotated pattern, bringing it into a new document from the Library is resulting in the object being placed as a group, while the Graphic Style itself is not added or transferred to the document.

I'm taking this further with the product team for investigation and will share an update here as soon as I have more information.

Wishing you a Merry Christmas, and thanks again for your patience and detailed testing.

I've totally deleted the illustrator folder, reinstalled in English, restarted CC-app, restarted laptop, but still get the same result: The graphic style is missing. Today I explained the use of graphic styles when rotated patterns are needed. But it turned out to be a 'no-go' when Libraries are used to transform them from one document to another. I hope Adobe will fix this soon, because I think it's really annoying that a Library has a weak spot here.

1. I make a pattern with horizontal lines. 
2. Apply that pattern to a square, or any other element.
3. Rotate the pattern 45°.. Not the object, just the pattern.
4. Make a new graphic style from this element. Any object that gets this graphic style applied has the pattern already rotated. Its too difficult to make a rotated pattern, so I choose to use graphic styles for that.
5. Ad this as an illustration to the library.
6. Make a new document, alt/option-drag it from the library to the new document. The pattern is added to the new document, but the graphic style isn't.

In older versions the graphic style was also copied to the new document. I can see that graphic styles in general can be copied through the libraries, but in this case it doesn't work with the rotated pattern.
