Steps to replicate: 1) In Safari, create a patient record and click Draw Pedigree in the Family History and Pedigree field. Draw a pedigree, save it, and save the record. When viewing the patient record, click the download button next to the pedigree and select "Image (PNG)" (see attached screenshot for details.)
Expected behaviour: a png image of the pedigree is loaded in a new tab.
Actual behaviour: If the pedigree was created in Safari, then the PNG image of the pedigree will always fail to load, regardless of whether it is opened in Safari or Chrome.
Export pedigree to png fails on both Safari and Chrome as png file is created empty.
Export pedigree to svg produces a blank page.
