Incorrect type on string-key fields when combined with `[string]`

Type Checking

Expected Behaviour

we have a (generated) class like

---@class GlobalModSettings
---@field ["heat-visualizer-updates-per-surface-per-tick"] ModSetting<int32>
---@field ["nixie-tube-update-speed-alpha"] ModSetting<int32>
---@field ["nixie-tube-update-speed-numeric"] ModSetting<int32>
---@field [string] ModSetting<(int32)|(double)|(boolean)|(string)|(Color)>

which has narrower types for the known entries and a general type for the "everything else" field, but when i then use this type like

local x = settings.global["heat-visualizer-updates-per-surface-per-tick"]

x is given the type from the [string] field, rather than the one that is an exact match for that specific string

未指定仓库文件或测试名称。首先通过 Visual Studio Code extension，在 Lua language server 中复现带注解的 GlobalModSettings 查找，然后跟踪索引字段的类型解析。完成的标准是，精确字符串键字段获得其更窄的类型，而不是更宽泛的 [string] 字段类型。
