Reproduction steps

I have the following code

local FONTFLAG_NONE = 0
local FONTFLAG_ITALIC = 0x001
local FONTFLAG_UNDERLINE = 0x002
local FONTFLAG_STRIKEOUT = 0x004
local FONTFLAG_SYMBOL = 0x008
local FONTFLAG_ANTIALIAS = 0x010
local FONTFLAG_GAUSSIANBLUR = 0x020
local FONTFLAG_ROTARY = 0x040
local FONTFLAG_DROPSHADOW = 0x080
local FONTFLAG_ADDITIVE = 0x100
local FONTFLAG_OUTLINE = 0x200
local FONTFLAG_CUSTOM = 0x400
local FONTFLAG_BITMAP = 0x800

---@alias FontFlags
---| `FONTFLAG_NONE` # 0
---| `FONTFLAG_ITALIC` # 1 (0x001)
---| `FONTFLAG_UNDERLINE` # 2 (0x002)
---| `FONTFLAG_STRIKEOUT` # 4 (0x004)
---| `FONTFLAG_SYMBOL` # 8 (0x008)
---| `FONTFLAG_ANTIALIAS` # 16 (0x010)
---| `FONTFLAG_GAUSSIANBLUR` # 32 (0x020)
---| `FONTFLAG_ROTARY` # 64 (0x040)
---| `FONTFLAG_DROPSHADOW` # 128 (0x080)
---| `FONTFLAG_ADDITIVE` # 256 (0x100)
---| `FONTFLAG_OUTLINE` # 512 (0x200)
---| `FONTFLAG_CUSTOM` # 1024 (0x400)
---| `FONTFLAG_BITMAP` # 2048 (0x800)

---@param name string
---@param height integer
---@param weight integer
---@param flags FontFlags|integer
---@return integer
---@nodiscard
function draw.CreateFont(name, height, weight, flags) end

Here, type completion does provide suggestion if param has not been filled

After that, i input a | character and open suggestion dialog again, and there's no more FontFlags type

I found a "hack" that works by changing function prototype

---@param name string
---@param height integer
---@param weight integer
---@param ... FontFlags|integer
---@return integer
---@nodiscard
function draw.CreateFont(name, height, weight, ...) end

However this hack is not ideal

Reproduce the issue in the Visual Studio Code extension with the supplied Lua annotations and function prototype. Start by comparing completion before and after entering | in the flags parameter; done means FontFlags suggestions remain available after the bitwise operator.
