This breaks the current implementation of electron-pdf because the ipcApi object that gets defined in the preload.js is not accessible from within the webpage's javascript itself. To handle the ready event, we inject a listener in exportJob.js#_executeJSListener that tries to use that object but fails because it is not defined in the page's context.
This can be solved in two ways:
Eplicitly disable contextIsolation when setting up the job in setupJob.js
Use the contextBridge api to expose ipcApi to the website's context.

As noted in the docs, the
