Roadmap planner overlaps other content in PDF export

Steps to reproduce:

1. Create a page with a multiple column layout
2. Add a roadmap planner macro in the left column, and some other content in the right column.
3. Export the page to PDF.

Expected result

Roadmap planner displays correctly, beside the content in the next column.

Actual result

Content in the right hand column, overlaps the roadmap planner macro in the left column

Workaround
Place roadmap planner macro in its own, full width section (no columns).
