And? Two simple facts... LibreOffice is _not_ a PDF editor, and PDF is _not_
intended to be an editable format. 


For this PDF, the pdfium based insert handles the area fills correctly, the
pdfio filter import does not.

Inadequacies of the PDF Import filter--pdfio (which breaks apart a PDF into
component Draw objects) are well known as are the issue here with clipping
these area fills (this should probably be closed as a duplicate of bug 86211).

Our move to pdfium for insertion of PDF as an image, with loss of "break" (with
its call the pdfio filter), gives very high quality raster rendering of PDF
into ODF documents. What the vast majority of users require and the direction
we've taken our handling of PDF.

Further work on the pdfio import filter is needed and will occur--though
personally I think export handling are the higher priority.

Meanwhile, Miklos continues to work with Google's pdfiumm based filter. We hope
the eventual introduction of a skia based integration to canvas will restore
vector based PDF rendering, but it is not there yet (bug 106581).
