Notes on annotations disappear when saving and re-loading
On Debian/testing I created a PDF file loremipsum.pdf, opened it in Evince 3.30.1 / Poppler 0.63.0 and added nine text highlights, each of them with a short text. Then I used the hamburger menu's "Save As..." feature to overwrite using the original file name. This is the file loremipsum.pdf.
When I re-open this ODF file using the same version 3.30.1 of Evince, the nine annotations are visible, but I can only click on four of them. The notes for the other five are inaccessible. Hovering over them, the cursor does not become a hand and nothing happens when I click on them.
BTW, opening the file with PDFStudio 12 demonstrates that the highlights' annotations are still all there in the document: .
This is an important bug since it amounts to some form of data corruption.
