Combining marks are not being positioned correctly

[Jakub Simek]

I am trying to typeset polytonic Greek in Affinity Publisher (2.1.1) on Mac. The Greek accents and breathings are encoded via combining marks, not precombined characters. A support for combining marks in a font is necessary for polytonic Greek because not every combination of letters and diacritics is provided by Unicode (and the usual fonts) as a precombined character. 

My sample text (for demonstration purposes) is:

Πεποίθησιν δὲ τοιαύτην ἔχομεν διὰ τοῦ Χριστοῦ πρὸς τὸν θεόν

This is encoded (UTF-16) as:

03a0 03b5 03c0 03bf 03b9 0301 03b8 03b7 03c3 03b9 03bd 0020 03b4 03b5 0300 0020 03c4 03bf 03b9 03b1 03c5 0301 03c4 03b7 03bd 0020 03b5 0313 0301 03c7 03bf 03bc 03b5 03bd 0020 03b4 03b9 03b1 0300 0020 03c4 03bf 03c5 0342 0020 03a7 03c1 03b9 03c3 03c4 03bf 03c5 0342 0020 03c0 03c1 03bf 0300 03c2 0020 03c4 03bf 0300 03bd 0020 03b8 03b5 03bf 0301 03bd

When pasting the string into Affinity Publisher, the diacritics are not positioned correctly over the base characters. The font is Times New Roman:

The same string is displayed correctly with the same font in Microsoft Word:

And it is also displayed correctly in InDesign as well with the same font:

So apparently Affinity Publisher does not position the combining marks properly.

I am attaching my Affinity Publisher sample file. There is probably a similarity to this issue: 

This problem makes it impossible for me to use Affinity Publisher for Greek projects (and for other use cases as well where combining marks are required).
