Adobe Experience Manager: Copy-pasting a container displays duplicated components

Description description

On AEM 6.5.20 and AEM 6.5.21, when you copy a container component and paste it in the page editor, the pasted container may appear to have its inner components duplicated.

This behavior occurs with the layout container component and the tab component.

Environments

AEM 6.5.20 and AEM 6.5.21

Resolution resolution

This is a temporary visual glitch (SITES-21890). Reloading the page editor will remove the duplicated components.

Install AEM 6.5.22 to mitigate the issue.
