This issue is common across all languages that use the q element.

When an English page contains a quotation in another language, the quotation marks used around that quotation (and inside it for embedded quotes) should be the English ones – not those of the language of the quotation. The same applies for other languages.

Currently, if the language of the quotation is declared on the q tag in HTML and that tag has a lang attribute, browsers instead set the quotation marks based on the language of the quote.

For more details, see this GitHub issue, which is being used to track this gap. Please add any discussion there, and not to this issue.
