When translating "Proteste in Hongkong 2019" from German to Dutch, the "Weblinks" section contains some items based on the Internetquelle template. When these are loaded in Content translation those templates appear duplicated in the source document.
Below you can see how the item of the second bullet point is shown in the source article, Visual Editor and Content translation:
|Article||Visual Editor||Content translation|
As shown above, when rendered in Content translation the template is duplicated ("massive proteste..." text appears twice one after the other, being the second one highlighted)
