Anchor on LaTeX Block Math does not work

[NeumoNeumo]

Describe the bug The block-ref anchor like ^285714 after a math block does not take effect.

To Reproduce Steps to reproduce the behavior:

1. Create a new quartz project
2. Write the following in the index.md

$a^2 + b^2 = c^2$ ^142857

$$
\sum_{n\ge 1} \frac {|\sin (n)|^n} n
$$

^285714

^428571

3. Build and open the index page. The formulae are rendered correctly as shown in

But the html is like

-- My ^285714 disappears.

Expected behavior <span class="katex-display"> should be <span class="katex-display" id="285714"> .
