js file to jsx format not work

[uptownboy7]

if i open js file, its default is js Highlight even i clicked [set Default to js files] before.

i edit react [.js] files but it doesn't recognize as JSX when i selected [set Default to js files]
the first time i clicked the option, it works.
but when i close brackets, and reopen the brackets, it initialized!
JS highlighter shows but not JSX highlighter

It Doesn't Work.

Yup. It actually should automatically identify the project as a React App, and then interpret any .js as .jsx. Anyone?
