After insertion of special character (in the same font as main character) it renders not as it should by font configuration. Specifically, it should be anchored to main character as it configured in font.
I suppose it is associated with the fact that inserted charater added in different span.

For me, the diacritic in the bottom paragraph is above the character (perfectly in the middle). So not like in your screenshot, where it is inside it.

I suppose I set to NEW, purely by observing the file.

In 3.6.7, the bottom paragraph looks the same as the top.

I suppose you haven't installed included font. Included font have anchors to specify combining position. The problem is if we have text with normal character and combining character in span, then LO shows combination of two characters as if there were no anchors. If font doesn't have anchors in tested character combination you won't see the difference.
