In the question "Resources for learning Mandarin Chinese", there is an answer which lists some Newspapers, and in particular mentions:
纽约时报中文网 [紐約時報中文網] - New York Times - displays articles as English-Chinese parallel text.
At the top of the mentioned Chinese-conscious website of The New York Times (https://cn.nytimes.com/), one can switch between "简体" (simplified characters) and "繁體" (traditional characters). It works as expected when viewing the articles in Chinese-only mode.
But ... when entering the dual side-by-side English-Chinese parallel mode (once you find an article of interest, one can do so by adding /dual/ trailing to the URL, or simply click on "中英对照"), all of the characters switch to "简体" (simplified characters).
Is there anything I am missing here, or is this really a technical issue/bug? Is there no way to show the parallel English-Chinese version of the article with "繁體" (traditional characters)?
