Wrong json-mode formatter chosen when specified in dir-locals file

[daut]

I'm trying to specify different formatters for three different modes in .dir-locals.el file. Here's how the file looks like.

((js-mode . ((apheleia-formatter . eslint)))
 (json-mode . ((apheleia-formatter . prettier-json)))
 (web-mode . ((apheleia-formatter . eslint))))

js and web mode files are correctly using eslint formatter, but json-mode incorrectly uses eslint as well. When I delete the first line from the above dir-locals file json-mode correctly has prettier-json set in the apheleia-formatter variable.

I'm suspecting this is caused by the fact that javascript-mode is json-mode's parent, but don't have an idea how to fix it. Are there any ways around this?
