Same unique id for each div generated by display_javascript()

[simzer]

After converting the attached notebook idtest.ipynb.txt
containing this content:

from IPython.display import display_javascript

display_javascript("console.log(element.id)", raw=True)`

display_javascript("console.log(element.id)", raw=True)`

with the following command to html:

jupyter nbconvert --to html --execute idtest.ipynb 

the generated output idtest.html.txt contains a <div> for each display_javascript() call with the same id:

<div id="dd594bf5-4609-4eb6-92a7-5521f50e2bfe" class="jp-RenderedJavaScript jp-OutputArea-output " data-mime-type="application/javascript">
...
<div id="dd594bf5-4609-4eb6-92a7-5521f50e2bfe" class="jp-RenderedJavaScript jp-OutputArea-output " data-mime-type="application/javascript">

According to the template in base.html.j2 the <div>s' ids are intended to be unique:

{% set div_id = uuid4() %}
<div id="{{ div_id }}" class="output_subarea output_javascript {{ extra_class }}">
