It looks like bug 36328 accidentally added a "note" parameter to HTML::Scrubber in C4::Scrubber. Looking at the HTML::Scrubber documentation, there is no "note" parameter. It looks like a bit of confusion because "comment" is both a HTML::Scrubber parameter and a C4::Scrubber type.
I inlined a fix for this in bug 40079
