Page with a Jira macro and an image inside of a table can't be exported to PDF

Issue Summary

If a page has a Jira macro and an image inside of a table, we won't be able to export it to PDF, causing an error during the export.

Steps to Reproduce

1. Create a page using the current editor
2. Add a Jira macro listing a few issues
3. Add a table and insert an image inside (reproducible with PNG images)
   This is an example of storage format that causes this problem:
   broken_storage.html
4. Publish the page and try to export it to PDF

Expected Results

The export should complete without problems

Actual Results

The export fails, throwing a generic error:

There was an error in the export. Please check your log files.

The following error is thrown in the backend

java.lang.IndexOutOfBoundsException: Index 1 out of bounds for length 1

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
