For example, on the page https://www.nationaltheatre.org.uk/artists/ronke-adekoluejo/ the name "Ronkẹ Adékọluẹ́jọ́" renders incorrectly. Minimum viable demo at https://codepen.io/edent/pen/qEaRyrz Actual results: WebKit doesn't render the combined characters properly, but Chrome does. The web font contains é (U+00E9) and both ́ (U+0301) & ̣ (U+0323). But doesn't include ẹ (U+1EB9) or ọ (U+1ECD). This means the following characters don't render well: ẹ ẹ́ ọ I think this is caused by the font-weight: normal; CSS property.
