### Expected Behaviour

Hello, thank you for LuaLS!

There is a small issue that we have found when formatting a Lua file and indentation;

```lua
local v = t[
key(1)
]
```

### Actual Behaviour

This is how the formatter leaves it;

```lua
local v = t[
key(1)
]
```

### Reproduction steps

https://github.com/defold/defold/pull/12995

1. In the Defold Editor's text editor, in a Lua script file, type
```lua
local v = t[
key(1)
]
```

2. Run the document formatter function with `Alt+Shift+F` or from the top menu `Edit > Format Document/Selection`
3. `key(1)` falls back to previous column

使用 Lua 程式碼片段和 Format Document 命令在 Defold 的內建文字編輯器中重現問題，然後追蹤處理方括號內運算式的 LuaLS 格式化路徑。完成的條件是格式化保留 key(1) 前的縮排，包括在連結的 Defold 重現中。
