High CPU usage (tsserver and typingsInstaller)

High cpu, files in excluded folder being watched

Steps to reproduce

Open vscode in an ember-cli project and run ember s to build and watch for changes. CPU usage of tsserver and typingsInstaller both jump up to 100% and remain there. typingsInstaller remains open even after vs code is closed, until the process is forcefully killed.

jsconfig.json:

{
  "compilerOptions": {
    "noEmit": true,
    "moduleResolution": "node",
    "lib": [
      "es2018"
    ],
    "target": "es2018",
    "baseUrl": ".",
    "paths": {
      "dugo-web/*": ["app/*"],
      "npm:dugo-lib": ["node_modules/dugo-lib"]
    }
  },
  "include": [
    "app"
  ],
  "exclude": [
    "public",
    "tests",
    "vendor",
    "node_modules",
    "tmp",
    "dist",
    ".git"
  ],
  "compileOnSave": false
}

tsserver.log
ti-19009.log
ti-18559.log
ti-18084.log

It's odd to me that although 'tmp' is excluded it is still being watched
