Font whitelist and clipboard.convert()

[TheEponymousBob]

Should adding a font to one's whitelist be reflected in clipboard.convert() for HTML when dealing with style attributes? I'm trying to render HTML from a legacy app that saves fonts as, for example, <span style="font-family: roboto;">Hello</span>.

I've updated the font whitelist and verified that it is going in to the registry. But when I trace through the convert() code, I reach clipboard.matchAttributor(), which checks a whitelist in STYLE_ATTRIBUTORS, and this does not seem to have been updated when the new font is registered.

I've put this in a CodePen. The console will show that only the monospace font is being recognised. Uncommenting the last two lines should show that the roboto font has been registered.
