Images in table cells disappear when exported to PDF

Images inserted inside a cell of a standard table in Confluence are no longer rendering when exported to PDF. This was working recently, perhaps this broke in the latest release?

To replicate:
1. Create a standard table on a Confluence page.
2. Insert an image inside a cell of this table.
3. Export the page to PDF.

See the above screenshot of a page as viewed in Confluence. An image inserted inside a table cell is visible, as well as the one outside the table. The same image attachment was used.

When exported to PDF as seen in the above screenshot, the image inserted in the cell does not appear.

This is using the latest version of Confluence OnDemand.
