Empty vertices in ink annotation #3209
Description
Description of the bug
The Annot.vertices of an ink annotation is empty. Annotation is visible in mupdf and other readers. Getting annotation xref and printing xref_object(xref) show that the vertices are in the dictionary. Inspecting the qpdf JSON dump comfirm vertex data presence. But printing annot.vertices gives the empty list (while annot.info is OK). Some relation to #525
How to reproduce the bug
import fitz
pdf = fitz.Document(filetype="pdf")
page = pdf.new_page()
page.add_ink_annot([[(300,300), (400, 380), (350, 350)]])
for a in page.annots():
print(a.vertices)
pdf.save("borrame.pdf") # Check the output PDF that the annotation is correctly drawn
output is [] instead of list of vertices
