Automatic update from web-platform-tests Avoid looking up empty font name in FontFaceCache When document.fonts.load() is called with font specification such as '1px ""' (containing two quotes) as the argument, CSS font property parsing parses this successfully as the empty string. FontFaceCache was not prepared to handle that correctly. Fix FontFaceCache to guard against that. Add test to actually ensure that this font specification's load promise resolves successfully. In parallel, raised https://github.com/w3c/csswg-drafts/issues/4510 in CSS WG to discuss whether it would make sense to reject such a font specification at the parsing stage already.
