Printing on Google Slides doesn't work with Shields up

[Brave-Matt]

Description

We had an old issue for Google services where Brave would force the user to save the [content] as a .pdf rather than initiating the print screen dialog:
#3694

This issue seems to have reappeared specifically for Google Slides. Attempting to print anything on Slides with Shields up forces the user to save the content as a .pdf. Attempting to print w/ Shields down displays the print screen dialog as intended:

Steps to Reproduce

1. Visit slides.google.com and open a presentation
2. Attempt to print a slide w/Shields up
3. Observe browser forces saving content as .pdf

Reproduces how often:

Always

cc: @ryanbr Looks like the print dialog show up ok with Shields down. Only an issue on Google Slides. Works fine (print dialog shows up) with Sheets and Docs with Shields down.

@rebron - regarding the label "workaround/shields-down"; does this label mean it will not be properly fixed, i.e as there is a workaround?
Thx

[rebron]

@twMat Only means that there is a workaround. We want a proper fix for it.

Looks like a fingerprinting issue, Allowing fingerprinting on slides.google.com cc: @pilgrim-brave

Sorry, but I am having this problem now and shields down is not helping. I can confirm printing works normally on Sheets, but not on Slides.

[ryanbr]

"plugins" fingerprinting.

Well, still not for me. Turning shields off makes it work.
