Code

$$
\begin{aligned}
\frac{D \boldsymbol{v}}{D t}=&-\frac{1}{\rho} \operatorname{grad} p+\frac{\mu}{\rho} \Delta \boldsymbol{v}+\frac{\lambda+\mu}{\rho} \operatorname{grad} \Theta+\frac{\Theta}{\rho} \operatorname{grad}(\lambda+\mu) \\
&+\frac{1}{\rho} \operatorname{grad}(\boldsymbol{v} \cdot \operatorname{grad} \mu)+\frac{1}{\rho} \operatorname{rot}(\boldsymbol{v} \times \operatorname{grad} \mu)-\frac{1}{\rho} \boldsymbol{v} \Delta \mu+\boldsymbol{g}
\end{aligned}

If \boldsymbol and \operatorname were gone, it works.

[WIP] investigation

only KaTeX: ⭕
markdown-it + katex plugin: ⭕
slidev: ❌

[antfu]

It turns out the markdown-it-katax is relaying on katex v0.6.0. Inlined and fixed.
