AFAICT, this is because the dotted circle is inserted in `pwGlyphs` but not in `pwcChars`, so it has no entry in `pwLogClust`. `UpdateClusters` does not know this, it pushes every glyph in `pwLogClust` forward at or beyond the insertion point. This pushes the matra's cluster entry forward to point at the dotted circle's glyph slot. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10704#note_137758
