Weird post attachment behavior in MCP report details

When a post has attachments and is reported, the report details view in the MCP has very strange behavior when it comes to attachments.

1) When the post has both inline and normal attachments, the order tends to get switched around. So it's possible that the inline attachment is moved to the bottom (normal), and the normal attachment is suddenly inline.

2) Inline attachments (particularly images) tend to get whole load of extra <br> elements inside of the <div class="inline-attachment">.
