A guide inside a symbol shows at the top-left corner of the canvas

Steps:

1. In a new document, draw a square and a small triangle in the middle of the canvas.
2. Select the triangle and choose View > Guides > Make Guides.
3. Select both and make them a symbol (F8).
4. Zoom out to see the whole canvas.

Result: The guide triangle appears at the top-left corner of the canvas, not inside the symbol. See screenshot of whole canvas, with one artboard in centre.

Expected: The guide stays with the symbol, where it was drawn.

Notes:

• The guide's real position is still correct: Break Link puts it back in the right place.
• Every copy of the symbol draws its guide at the same corner.
