Having opened the network tab in Chrome (Version 87.0.4280.141 (Offizieller Build) (64-Bit)), I see all the requests sent by the browser.
Expecting content when I export what I see as HAR file: all requests are in the HAR file
Observerd behavior: some requests are missing
--> are there any rules which make that some requests are not exported in the HAR file? Note that it works fine with FF(84.0.2)
