Tor browser uses Chinese-style glyphs to display Japanese
In Tor browser 5.5.1 version (en_US), if I visit https://en.wikipedia.org/wiki/Han_unification#Examples_of_language-dependent_glyphs the browser correctly shows Japanese-style glyph variants in the ja column.
However, on most actual Japanese web pages, Chinese-style glyphs end up being used. This happens even if I select "Japanese" in the View->Character Encoding menu (I know that character encoding and glyph variant are two separate things, but a Japan-specific character encoding should be taken as an indicator that Japanese glyph variants should be used).
For example example, if I search for the characters from the Wikipedia table on this page - http://www.aozora.gr.jp/cards/001779/files/56648_58207.html - in every instance the simplified Chinese variant is used instead of the Japanese glyph.
