Incorrect symbol positions from documentSymbol

[stevearc]

I'm seeing some incorrect values coming back from documentSymbol

Repro:

• Create a new vue project with npm init vue@latest
• Open the src/App.vue file and trim it down to be just the following (this is just to reduce the number of results and make it easier to read):

<template>
  <header>
    <img alt="Vue logo" class="logo" src="./assets/logo.svg" width="125" height="125" />
  </header>
</template>

• Open the file with any text editor that has a LSP client and issue a textDocument/documentSymbol request

This produces the following:

[
  {
    "containerName": "",
    "kind": 8,
    "location": {
      "range": {
        "end": {
          "character": 11,
          "line": 3
        },
        "start": {
          "character": 2,
          "line": 1
        }
      },
      "uri": "file:///home/stevearc/vue-project/src/App.vue"
    },
    "name": "header"
  },
  {
    "containerName": "header",
    "kind": 8,
    "location": {
      "range": {
        "end": {
          "character": 88,
          "line": 2
        },
        "start": {
          "character": 4,
          "line": 2
        }
      },
      "uri": "file:///home/stevearc/vue-project/src/App.vue"
    },
    "name": "img.logo"
  },
  {
    "kind": 2,
    "location": {
      "range": {
        "end": {
          "character": 0,
          "line": 4
        },
        "start": {
          "character": 10,
          "line": 0
        }
      },
      "uri": "file:///home/stevearc/vue-project/src/App.vue"
    },
    "name": "template"
  }
]

You can see that the "template" symbol claims to start on line 0 character 10. It should be starting on line 0 character 0. Character 10 is actually a position that does not exist in the file (<template> only has 10 characters, and character is 0-indexed).
