Python vs JS result mismatch

[amjadtaleb]

I have this part of a document:
# [Authors](#authors) {#authors .authors}

that renders to the result below in JavaScript using markdown-it-attrs@4.1.6:
<h1 id="authors" class="authors"><a href="#authors">Authors</a></h1>

and to this result in python using mdit_py_plugins.attrs.attrs_plugin:
<h1><a href="#authors">Authors</a> {#authors .authors}</h1>

I use JS for input, where users can see a live preview of their text, and render it somewhere else using python.

I checked the JS code and it explicitly trims the blank space between blocks (or that's what I could understand from it), is there a option that I can set to make the mdit_py_plugins.attrs.attrs_plugin follow what the js plugin does?
