Typescript suggestions based on defined types not working

Bug Reports
1

Describe the Bug

this.user.positions has the type Position. Position is defined in declarations.d.ts as a global type (as are most of my types). If I type:

 this.user.positions.push({
[start typing here/press ctrl-space to bring up suggestions]
})

I do not get suggestions based on the Position type. I also do not get AI multi-line completions that are based on the defined type. Not getting them in the manually brought up suggestions window is something I’ve noticed for a while, but not getting good AI completions is new.

Steps to Reproduce

  1. Define an object type in a global declarations file, e.g. /src/declarations.d.ts:
declare global {
	type Position = {
            symbol: string
            ...
         }
         type User = {
               positions: Position[]
         }
}
  1. Add:
    "files": ["./src/declarations.d.ts"]
    to tsconfig.json
  2. In any .ts file:
let user: User = {
       positions: [{
             [try suggestions/completions here...they are wrong for me]
}]

Expected Behavior

I expect for both the suggestions window that’s brought up manually by ctrl-space (for me) and for the more complete/multi-line AI completions to be based on the defined type.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Yes, I’ve restarted the IDE and still have the issue.
