Hi,

The Live Preview mode does not render white lines correctly around “$$ \math $$”.

### Steps to reproduce

The following text is not rendered in the same way in the preview mode and in the live preview mode.

"

We can thus write the following

$$

\begin{aligned}

\frac{\mathbb{E}[e^{x_t(\beta-\gamma)}]}{\mathbb{E}[e^{x_t \beta_t}]}&= \frac{e^{(\beta_t-\gamma)\mu t +0.5 (\beta_t-\gamma)^2\sigma^2 t}}{e^{\beta_t\mu t+0.5\beta^2 \sigma^2 t}}

\end{aligned}

$$

Substituting and simplifying, we get…"

### Expected result

→ The white lines around the math part should be invisible in Live Preview (as they are in the normal preview mode). Typora handles this correctly.
