Browser Development • Re: CSP used for spying on blocked domains(?)

Btw, https://www.dhl.de/de/privatkunden.html causes Pale Moon to say:
Content Security Policy: Couldn’t process unknown directive ‘script-src-elem’ 1 (unknown)

The element is used as
script-src-elem 'self' 'unsafe-eval' 'unsafe-inline'

Is this script-src-elem not yet implemented in Pale Moon, or is it incorrectly implemented by the web site?
