How to activate the RTD flyout menu?

[12rambau]

This issue was initially posted on SO but the problem seems to be a bug so I'm moving here.

Original SO post

I'm using Sphinx and ReadTheDocs to build the documentation of my project.

I want to display several version to my end user so I built several branch in my admin area :

But when I'm displaying the doc in my browser (https://sepal-ui.readthedocs.io/en/v_1.1.0/), I cannot click on the flyout menu and change version.

Is it normal and how to make it functional ?
I use a readthedocs.yml file (link). Am I missing something ?

Edit

spoiler alert, the problem only occured on Safari, If I open my documentation on other browsers it work like a charm.

MacOS BigSur 11.1
Safari 14.0.2

@12rambau probably again a safari issue ..

Do you see this on other websites as well? Or only with this theme? (eg https://requests.readthedocs.io/en/master/ uses a different theme and also has a readthedocs widget)

I see the other one. That's why i headed to SO first I was thinking I was missing a config param

here is the full JS error I found in my console when clicking the flyout :

the bug resolved itself via Safari or RDT update....
