vscode.executeSelectionRangeProvider returns array of empty objects

By looking at the source there is a (still) undocumented command vscode.executeSelectionRangeProvider which is supposed to work similarly to other execute...Provider commands.

When running the following code inside extension

  const result = await commands.executeCommand(
      'vscode.executeSelectionRangeProvider', window.activeTextEditor!.document.uri,
      [window.activeTextEditor!.selection.active]);
  console.info(result);

and looking at the result in DevTools I see that the size of returned array looks valid but all objects (that are supposed to be of type SelectionRange) are empty.

It's important to note that expand/shrink commands work normally in editor so it's just extension host that receives empty objects.

BTW, by looking at command's test in

vscode/src/vs/workbench/test/electron-browser/api/extHostApiCommands.test.ts

Lines 799 to 801 in cb865f9

	let value = await commands.executeCommand<vscode.SelectionRange[][]>('vscode.executeSelectionRangeProvider', model.uri, [new types.Position(0, 10)]);
	assert.equal(value.length, 1);
	assert.ok(value[0].length >= 2);

I see that only array size appears to be tested (which works correctly) but not array contents.

Yeah, looks like this is using the wrong type...
