hotfix: certificate pdfs are blank when using browserless (#1935)

Browse Source 
Certificates have suddenly become blank when using browserless and
Chrome CDP.

This change introduces a workaround that involves reloading the
certificate pdf. Which is hacky but seems to work for now, a better
solution should be found in the future.
