Fix comment syntax inside jsx

[goodmind]

Temporary workaround for #7672

function Component<T>(props: {|type: T|}) {
  return null
}

const el = <Component /*::type={1}*/ />

[gabelevi]

What's the use case for this? Has this been requested?

[goodmind]

@gabelevi isn't it more consistent for comment syntax to work everywhere?

[goodmind]

@gabelevi I updated main post

[gabelevi]

Generally looks good to me!

A lot of the code looks copy/pasted. Can you move it into a helper function?

[goodmind]

I can't test it now, but I'm not sure if this would be allowed too?

</*::Test*/ />

If it is, I would like to disallow it probably

[goodmind]

@gabelevi I'm going to close it because I'm not really want to introduce some unexpected behaviour here with jsx, also I think this is not worth it
