User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

When I use
<article>
<details close ><summary>This is a test</summary>
<iframe width="100%" height="300px" frameborder="0" allowfullscreen src="https://framacarte.org/en/map/apparts_88475?scaleControl=false&miniMap=false&scrollWheelZoom=false&zoomControl=true&allowEdit=false&moreControl=true&searchControl=null&tilelayersControl=null&embedControl=null&datalayersControl=true&onLoadPanel=undefined&captionBar=false"></iframe>

<a href="https://framacarte.org/en/map/apparts_88475">See full screen</a>

</details>

The content of the iframe doesn't load when I expand the section.

With
<details open> it's works...

Actual results:

iframe stay grey (not loading)

Expected results:

iframe should load.

Reproduced on the latest versions of Firefox Beta 90.0b10 and release 89.0.1.

If enabled Fission, the problem is gone.
