Hi and thanks for this really handy plugin!

I noticed that when I run a search and when I open a page with a Mermaid diagram that contains a search result (therefore highlighted), the Mermaid elements show the highlight html code:

In another project, it also prevents the diagram for being displayed.

Could you check if you can reproduce this issue?

I use the following extensions that I imagine should not have any impact:

'sphinx.ext.ifconfig', 'sphinxcontrib.spelling', 'sphinxcontrib.mermaid', 'sphinx.ext.todo', 'sphinxprettysearchresults', 'retina_images'.

Thank you.
