Unable to use @enum or @alias: duplicate-doc-alias

[fatboychummy]

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Windows

What is the issue affecting?

Annotations, Type Checking, Completion, Diagnostics/Syntax Checking

Expected Behaviour

To be able to define an alias like so:

---@alias AliasName
---| '"value"'  # comment
---| '"value2" # comment

Actual Behaviour

No matter the name I choose for the alias, it states it is a duplicate. This occurs with @enum as well.

See the letter spam below

Reproduction steps

1. Define an alias, with a completely random name
2. see duplicate-doc-alias warning.

Additional Notes

This isn't the biggest issue in the world, though it's stopping completion and annotations in some areas. I can easily disable the warning, but would like to know if I have actually accidentally duplicated something.
