Error: Illegal argument: range

I get this error in the extension host log:

Here's a minimal reproducer file:

<?xml-model href=""?>
<root>
</root>

The problem stems from this line: https://github.com/microsoft/vscode/blob/b1a74f6fffd7018db0b4df54d2a028e7c4c4b3ef/src/vs/workbench/api/common/extHostTypes.ts#L775 ; if the range is 0 long, VS Code doesn't like it. We should avoid suggesting a document link if the length of the link range is 0.
