hi @Camille_Di_Vincenzo1 I was able to find out what is cause the issue but I can’t fix it as is related to Splide. On video you can see that dots are shown when aria-busy is changing fro false to true`
This has something to do with accessibility aria-live more info on MDN
There were some issues with aria-busy for speech but it is fixed now.
Sorry I can’t help further but you have at least some starting point. There should be possibility to force aria-busy to have false statement but not sure if it is a correct way to fix it. You may ask developer on GitHub to register an issue.
