**To Reproduce**

```ts
import { Trans } from '@lingui/macro'

export default function Component(props) {
return Hello, {props.world ? world : guys}
}
```
**Expected behaviour**
```ts
import { Trans } from '@lingui/react'

export default function Component(props) {
return (
:
}}
/>
)
}
```
**Actual behaviour**
```ts
import { Trans } from '@lingui/react'

export default function Component(props) {
return (
world : guys
}}
/>
)
}
```

Start with the related upstream pull request at https://github.com/lingui/js-lingui/pull/1436 and reproduce the shown TypeScript example through the SWC plugin. Trace how nested Trans macros inside a conditional expression are processed; done means both branches become self-closing Trans elements with ids of "world" and "guys" as shown in the expected output.
