Expected Behaviour

Actual Behaviour

Reproduction steps

  1. Open a new Lua file
  2. Type in this snippet:
---@alias someType
---| "#"

---@type someType
local someValue
  1. The hover type info for someType will contain miscellaneous characters -- "

Additional Notes

This issue goes away when omitting the last quotation mark:

---@alias someTypeHack
---| "#

---@type someTypeHack
local someValue

image

I haven't been able to reproduce this with any other special character.

This also pushes anything after the # character into a comment to the side.

---@alias someType
---| "#tag" -- comment

---@type someType
local someValue

Disabling all libraries did not remove the issue, and I have no plugins enabled.
