Subject: [PATCH] editor: Prevent underlines from appearing in minimap (#48510)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I noticed that the minimap seems to render underlines with the same
thickness as the main editor, which looks a bit off. This becomes much
more noticeable when enabling `semantic_token_rules` (due to the
increased number of underlines):

```json
"global_lsp_settings": {
  "semantic_token_rules": [
    {
      "token_modifiers": ["mutable"],
      "underline": true,
    },
  ],
}
```
Looking at the existing code, I found that diagnostic underlines already
check `editor_style.show_underlines` to ensure they are only displayed
in the main editor. To maintain consistency, I applied the same
filtering logic to `chunk_highlight` so that these underlines are no
longer rendered in the minimap.
