Will allowing HTML5 Canvas data in RFP fallback to FPP? (lemmy.ml)

Since version 118+, Firefox introduced FPP (Finger Printing Protection) which is in short water downed version of RFP (Resist Finger Printing).

FPP is enabled by default from version 119 onwards if you enable ETP (Enhanced Tracking Protection).

FPP randomizes canvas data subtly than RFP, which is why RFP breaks some sites. So, my question is, if we allow canvas data extraction for a broken site will it fallback to FPP's subtle canvas randomization, or allowing it will expose canvas data completely if we have ETP enabled?

Thanks for explainaing!

Why bother creating an image though? Cant they just generate a random hash or id?
