I had this exact same issue https://github.com/rails/jsbundling-rails…

…/issues/76\#issue-1115571908

Better explained in a later comment https://github.com/rails/jsbundling-rails/issues/76\#issuecomment-1022695521

And I'm trying this solution https://github.com/rails/jsbundling-rails/issues/76\#issuecomment-1051248565

I would have said the solution makes not only images, but also .js and .css lose the fingerprint functionality, but for whatever reason it's still fingerptinting everything except images..
