subscript on large parenthesis not at the bottom

If you have a fraction surrounded by parentheses, sometimes you want to put a subscript on the right parenthesis. In MathTexEngine, the subscript appears vertically centered instead of at the bottom.

I'm trying this in Makie.jl:

```
using GLMakie

f = Figure()
display(f)
Label(f[1, 1], L"\left( \frac{dy}{dx} \right)_0")
```
