https://lists.w3.org/Archives/Public/www-style/2016Dec/0108.html raised some use cases for ruby auto-hiding other than strict string equality. Many of the examples would require custom rules (which could be done manually with visibility: collapse), but some of these could be automatically solved by stripping white space and/or matching via NFKC. Should we enable such normalization for auto-hiding string comparison?
