Sample SVG file
Suppose you create a drawing and associate some text to it. If you apply OpenType substitution tables to the text and export to SVG, the font is ignored and a substitution used, breaking the formatting. Notice that OpenType tags work within Draw, it's the export that fails.
Problem is present in 6.4 but also in 7.1
The attached SVG file was created with Draw. The first line in the left box was created using
as font. The third line was created selecting the word Superscript and applying
as font to it. The right box was created with normal "character effects."
PDF export works as intended.

Original ODG file (it uses Libertinus Serif font)
The ODG file used to create the SVG export.

Exported SVG with no issue
I get a different result and it seems fine. Already fine for me in the latest of 7.1 Linux bibisect repo.
Can you re-test it?

Sorry, I did not have Libertinus installed. I reproduce that the left superscript is gone with the export.
