Matlab report generator - change of figure font during report generation

I have an issue with processing .fig images in Matlab report generator toolbox. The issue started after Matlab upgrade from 2019b to 2020b and it happens only for some figures.

Figure is transferred to from fig to svg with following code:

figures = openfig(pathToFig,'invisible');
fig = Figure();
fig.SnapshotFormat = 'svg';
tmpname = tempname;
print(gcf, tmpname,'-dsvg','-painters');
formImg = FormalImage([tmpname '.svg']);
formImg.Caption = 'Description'
formImg.Height = '6in';
add(chapter,formImg);
add(chapter,Paragraph());

Figure stored as .fig has normal sans-serif standard font:

But after proccesing using above code, following style appears in PDF

Should I specify some option when I am saving original figure to .fig format? I am confused with this because in 2019b everything was working fine and after upgrade to Matlab 2020b the font has chnaged for some type of charts.

I am having this same issue. Did you ever find a solution?

I have added to this line when I am saving figures. I am not sure if it is needed for newer version. I haven't tried to removing it.

set(gca, 'FontName', 'Arial');
