Review Comment:
**Suggestion:** Adding `z-index` on `.ace_gutter` without setting a
positioning context (position: relative/absolute/fixed) is ineffective; make
the gutter positioned so the z-index takes effect and the intended stacking
order is reliable. [logic error]
**Severity Level:** Minor ⚠️
```suggestion
position: relative;
```
<details>
<summary><b>Why it matters? ⭐ </b></summary>
Technically z-index only affects stacking order on positioned elements;
adding position: relative ensures the gutter's z-index will be honored. It's a
small, targeted CSS fix to make the intent explicit.
Be mindful that adding positioning can subtly affect layout, but in this
case position: relative is the least intrusive option.
