(automatically) discarding pdf files

It seems that loaded pdf files are not discarded automatically by Auto-Tab-Discard. They can be discarded using the "Discard Tab" context menu, but when using "Discard All Other Tabs" all loaded pdf files stay loaded. This can also be seen in the Task Manager (about:performance), where pdf files are still listed, and all included a "resource://pdf.js/build/pdf.worker.js" as worker.

Is it possible to add (automatic) discarding of pdf files?

Using Firefox 66.0b13, Auto-Tab-Discard 0.3.1

True. The script is not being injected to the PDF files.
