Outside hybridMode, hover might show result of `_VLS_ctx` instead of particular property (off-by-one offset bug)

Steps to reproduce

1. hybridMode: false
2. Consider example file below
3. Hover over the 1st character of a JS reference inside template, l is the easiest to try.

<script setup lang="ts">

/**
 * docs have to be removed in quick nav, preserved in quick doc!
 */
let local = 323 as number | null;
let l = 323 as number | null;

local;
</script>

  <div v-text="local"></div>
  <div v-text="l"></div>
  <div>{{local}}</div>
</template>

Any additional comments?

This is affecting WebStorm sadly, as we're not using hybridMode. I've checked and we sent the same offsets as VSCode does, but in hybridMode, Vue LS returns

[Trace - 16:57:08] Sending request 'textDocument/hover - (20)'.
Params: {
    "textDocument": {

    "position": {
        "line": 11,
        "character": 15
    }
}
