Writer-exported PDF with wrong margins

Consider the attached PDF, exported from Writer. It has A4 paper size, one RTL paragraph (with LTR text), and a horizontal line between the text boundaries. Its margins are 2 cm on each side.

However, when we open the document in Draw, we get margins of:

From left:   1.90 cm
From right:  1.00 cm
From top:    2.00 cm
From bottom: 4.00 cm

which is both wrong and nonsensical. The content is placed reasonably, however - it's just at an offset from the right margin.

Seen with:

Note: Not seeing that behavior using the Writer PDF import filter.

PDF export with LTR

Hmmm, I don't think RTL is the issue. If I export the same file, aligning the text to LTR, the margins are the same as the RTL file. 

It might have to do with the horizontal bar in the document. I get the similar (if not worse) results with a simple rectangle shape created from Writer. I will attach sample files shortly.

Steps: 

1. Open Writer
2. Insert rectangle shape
3. Export as PDF
4. Open file created in step 3 in Draw

Result: margins in Draw do not match the margins from Writer.

It's the same result in the oldest of Linux 43all bibisect repo. I should ask about this in the dev chat.
