What is the issue affecting?

Annotations

Expected Behaviour

The ability to define multiple return values for a field annotation.

Actual Behaviour

Any non-identifier symbol following a type is treated as a comment or a break.

Reproduction steps

1. Create a field with a comma separated return type.
2. See that anything following the comma is treated as a comment.

Additional Notes

---@class Color
---@field [string] Color,string
Color = {}

,string is highlighted as a comment.

---@class Color
---@field [string] Color, string
Color = {}

, is highlighted as a symbol, string is highlighted as a comment.

An example of fields with multiple return types are the named color lookups in the Tabletop Simulator API:
https://api.tabletopsimulator.com/color/#colorblue

local color, name = Color.Blue
print(color) -- Color: Blue { r = 0.118, g = 0.53, b = 1, a = 1 }
print(name) -- Blue

local color, name = Color.Red
print(color) -- Color: Red { r = 0.856, g = 0.1, b = 0.094, a = 1 }
print(name) -- Red

Start by reproducing the annotation parser behavior with the provided Lua snippets, focusing on how comma-separated types after an @field declaration are tokenized. Done means multiple return types such as Color,string are recognized as annotation types rather than treating the remainder as a comment; add or update coverage if the repository has relevant parser tests.
