**Additional notes**
* Not reproducible with the new UI
* If save to pdf or actual printing is done previously with the new UI, than going to the old one,  the issue is no longer reproducible (but only setting print.tab-modal.enabled to true doesn't make any difference)

**Suggested severity**
* S2
