formula format content lost format info

[BBboy01]

The formula content after this.quillEditor.getSemanticHTML() lost class and data-value attrs, after save the content and set that content as new content, formula can't display correctly.

<div><span>\tan\theta = \frac{\triangle y}{\triangle x}=\frac{(y+\triangle y)-y}{\triangle x}</span> -------------------- (2)</div><pre data-language="javascript">
const a = 1;
</pre><div></div>

just open an issue on quilljs and or the formular module for it, please.

I want to stick to the best practices for quilljs usages and so i will stick to use getSemanticHtml.
