Paragraph highlighting "destroys" webpage

[chseifert]

To reproduce

1. goto https://www.royalcollection.org.uk/collection/search#/3/collection/912265/sir-john-godsalve-c-1505-1556 (there is a green highlight, but it does not outline a paragraph)
2. click "people involved" on the left side, normal expected content would be:
   Creator(s)
   Hans Holbein the Younger (1497/8-1543) (artist)
   Acquirer(s)

• with activated extension, the page still contains the content from the tab "description"
