When I added source maps to PostCSS I mistakenly assumed that `.source`
on a node could be `undefined`. The comment above the property in
PostCSS says that `source` can be `undefined` but this is a commentary
on the value upon **access** not its expected value on **write**:
```ts
declare abstract class Node_ {
/**
* …
*
* The nodes that are created manually using the public APIs
* provided by PostCSS will have `source` undefined and
* will be absent in the source map.
*
* …
*/
source?: Node.Source
}
```
Rather, what these types mean is that *if the property exists* it must
be defined. But otherwise the property can be missing if a node has no
source location metadata. This generally wasn't a problem with the
string-returning APIs but the `toJSON()` API in PostCSS expects that
`source` is defined if present. This caused a crash because our license
comment doesn't have a source location.
I've addressed this by deleting the `source` property from the node if
source location data is not available.
Fixes #18082
