I think I've found a font rendering bug in #Firefox (and possibly Safari).

On the National Theatre website, Ronkẹ Adékọluẹ́jọ́'s name doesn't embolden characters with diacritical marks.

As far as I can see, the included Web Font contains é (U+00E9) and both ́ (U+0301) & ̣ (U+0323).
But doesn't include ẹ (U+1EB9) or ọ (U+1ECD).

Any thoughts on what's causing this and whether it is worth reporting?

@Edent that's not a bug, is it? If your font doesn't have the characters it's meant to display, then the characters display in some fallback font that _does_ have them. It's not ideal but it's hard to see what ought to happen in that situation. But you know that, so I feel like I've misunderstood the issue?
@sil
It doesn't have the character "ẹ́"
But it does have the character "é" and the low dot combinator.
So it should successfully combine the two.
At least, it does in Chrome.
@Edent ah, understood! then yeah, no idea, sounds like you're right and they ought to be doing better!
