Describe the bug
tsc --build fails with error Property 'dpWrapMenuRef' of type 'Ref<HTMLElement | null, HTMLElement | null>' is not assignable to 'string' index type 'Function'.
Interface PublicMethods inherits from MethodOptions and here is defined [key:string]: Function, so always a function is expected and type Ref<HTMLElement | null, HTMLElement | null> is not assignable to type Function.

To Reproduce
Steps to reproduce the behavior:

1. Use the following tsconfig.json:

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "allowUmdGlobalAccess": true,
    "allowUnreachableCode": false,
    "allowUnusedLabels": false,
    "exactOptionalPropertyTypes": true,
    "forceConsistentCasingInFileNames": false,
    "incremental": true,
    "lib": [
      "ESNext",
      "DOM"
    ],
    "module": "ESNext",
    "moduleResolution": "Node",
    "noEmitOnError": true,
    "noUnusedLocals": true,
    "noFallthroughCasesInSwitch": true,
    "noUnusedParameters": true,
    "removeComments": true,
    "strict": true,
    "target": "ESNext"
  }
}

2. Add "@vuepic/vue-datepicker": "10.0.0", to dependencies in package.json.
3. Execute tsc --build.

No build errors.
