Possible typo for MimeTypeArray interface

Code

// A *self-contained* demonstration of the problem follows...
// Test this by running `tsc` on the command-line, rather than through another build tool such as Gulp, Webpack, etc.

Expected behavior:

Based on https://developer.mozilla.org/en-US/docs/Web/API/MimeTypeArray, some of MimeTypeArray properties should return MimeType interface instead of Plugin interface.

interface MimeTypeArray {
    readonly length: number;
    item(index: number): MimeType;
    namedItem(type: string): MimeType;
    [index: number]: MimeType;
}

Actual behavior:

Some of MimeTypeArray properties return Plugin interface.

interface MimeTypeArray {
    readonly length: number;
    item(index: number): Plugin;
    namedItem(type: string): Plugin;
    [index: number]: Plugin;
}

I'm surprised that the typo has been around for four years since ad449ce0fae354df03e97e7e8507b9e4f1880001.
