Angular 8+ tsconfig Path Aliases not Recognized in .spec files

I am working on some Angular testing and my spec files will not recognize my paths and they give me a red squiggle import warning in VS Code (and show up in Problems) despite the fact that they work in every other way (testing works, etc.). I am assuming this is a tsconfig issue and not a linting issue as the error it gives me is: Cannot find module '@feature/<reference path>.<file type>'.ts(2307)

It functionally doesn't affect me much, but it is annoying (and kills automatic imports).

tsconfig.json paths:

...
    "paths": {
        "core-js/es6/*": [
            "node_modules/core-js/es/*"
        ],
        "core-js/es7/reflect": [
            "node_modules/core-js/proposals/reflect-metadata"
        ],
        "@core/*": [
            "src/app/core/*"
        ],
        "@shared/*": [
            "src/app/shared/*"
        ],
        "@feature/*": [
            "src/app/feature/*"
        ],
        "@test/*": [
            "src/test/*"
        ],
        "@/*": [
            "src/*"
        ]
    }
...

tsconfig.spec.json and tsconfig.app.json paths (note standard folder structure from angular-cli):

{
    "extends": "../tsconfig.json",
    "compilerOptions": {
        "outDir": "../out-tsc/spec"
    }
}

angular.json

...

                "builder": "@angular-builders/jest:run",
                "options": {

                        "src/styles.scss"
                    ],
                    "scripts": [],
                    "assets": [
                        "src/favicon.ico",
                        "src/assets",
                        "src/manifest.json",
                    ],
                    "stylePreprocessorOptions": {
                        "includePaths": [
                            "src"
                        ]
                    }
                }
            },
            "lint": {

                        "src/tsconfig.spec.json"
                    ],
                    "exclude": [
                        "**/node_modules/**"
                    ]
                }
            }
