Context Breaks — Bug report

The new context break feature in 21.4 has a bug. Being able to map a paragraph style to an <hr /> tag is terrific. It is a massive improvement for EPUB developers. That said, there is a bug. 

When an assembled image (like a series of grouped items, or similar) are set to rasterize as a context-break image, and the paragraph tag that it sits in is set to export as an <hr />, the image goes missing. As this is a very common in trade publishing, it would be useful to address this issue.
