TypeScript: Unable to override the id accessor of a Component with string

[frank-weindel]

A user on our forums made a post reporting that when they add a get accessor for the property id to a Component class like so...

class MyComponent extends Lightning.Component {
  get id() {
    return 'BrowsePage'
  }
}

...it triggers the following TypeScript errors:

Property ‘id’ in type ‘Item’ is not assignable to the same property in base type ‘Component<ItemTemplateSpec, TypeConfig>’.
  Type ‘string’ is not assignable to type ‘number’.
‘id’ is defined as a property in class ‘Component<ItemTemplateSpec, TypeConfig>’, but is overridden here in ‘Item’ as an accessor.

The user, as well as another user who chimed in, both implied that they use the id property override to inform the HTML tag that is produced by the Lightning Inspector. The IDs in these HTML elements are then used in Cypress testing for QA validation.
