Dragged JPEG becomes a gray rectangle after switching documents

[jpsimmons]

Description:

An image dragged from a JPEG document into another document can become invisible and be replaced by a solid gray rectangle corresponding to its bounding box.

This is an old problem that had disappeared for several versions but appears to have returned.

Steps to reproduce:

Create a new document.
Open a JPEG as a document in VectorStyler.
Drag and drop the image from the JPEG document into the new document.
Create another new document.
Select the first new document to make it visible again.

Result:

The dragged-and-dropped JPEG is no longer visible. Its bounding box is instead filled with solid gray. I have not found a way to make the image visible again.

Expected result:

The JPEG should remain visible when switching between documents.

I have attached the source JPEG used for the test and a VectorStyler document in which the problem occurred.VS_doc.vstyler
