#3268 [GUI] LaTex Rendering Issue NOT Working on 0.2.0-beta

Beschreibung

Hi,

This is a follow-up on [Not Rendering Latex](https://github.com/Niko1221/Strata/issues/2723). I have re-tested Latex rendering in 0.2.0-beta and the problem still persists.

Model: qwen3.8-flash-next-iq3_xxs
GPU: RTX2060 12GB VRAM
RAM: 64GB
OS: Ubuntu 26.04

What should be displayed as 

`Tunnel-Through-a-Planet Problem
Part 1 — Equation of Motion via Gauss's Law

Apply Gauss's Law for gravity to a sphere of radius $r \le R$ concentric with the planet:

$$\oint \vec{g}\cdot d\vec{A} = -4\pi G\, M_{\text{enc}}(r)$$

By spherical symmetry, $\vec{g}$ is radial and constant on the Gaussian sphere, so:

$$g\,(4\pi r^2) = -4\pi G\left(\tfrac{4}{3}\pi r^3\rho\right)$$

$$\boxed{g(r) = -\frac{4\pi G\rho}{3}\,r}$$`


looks like:
