I tried replacing the jsx tag with the react-jsx tag in this question:

VSCode Prettier reformat adds {" "} when adding new line between html tags

The new tag never got added. I tried multiple times to add the tag in following edits, but the tag never got added.


The tag [react-jsx] is a synonym of [reactjs]; you can see this on the Tag Synonyms page. So basically you're adding the same tag twice, and the system picks one: the 'master' tag, which is [reactjs].

  • Thanks for pointing that out. There was absolutely no way to determine that from the UI. You just have to know somehow that it's a synonym (and that the concept of synonyms even exists). – Dmitry Shvedov Mar 13 '19 at 20:34
