Allow Typescript to detect when imported html relative paths are incorrect

TypeScript Version: 2.8.1

Search Terms: html template import

Code

In global.d.ts:

declare module '*.html' {
    const value: string;
    export default value
}

Somewhere else in code:

import templateHtml from './SOME_PATH_THAT_DOESNT_EXIST.html'

Expected behavior:
I expect that Typescript will still attempt to parse the string in 'from' and tell me if it can't find any matching files, as it is a relative path.

Actual behavior:

No error or warning is emitted, so any typos in the path won't have a problem until running the app.

Start with the module-resolution and type-checking paths for the ambient '*.html' declaration shown in global.d.ts, using the import example as the reproduction. The work is done when a missing relative HTML path produces a diagnostic while a matching path continues to resolve through the declaration.
