Bug

Provide detailed reproduction steps (if any)

When building ckeditor4-docs, webpack Angular compilation (starting from 2.0.0 version) throws An accessor cannot be declared in an ambient context TS errors:

The lines to blame are:

ckeditor4-angular/dist/ckeditor.component.d.ts

Lines 42 to 43 in 6313ee6

	set data(data: string);
	get data(): string;

ckeditor4-angular/dist/ckeditor.component.d.ts

Lines 50 to 51 in 6313ee6

	set readOnly(isReadOnly: boolean);
	get readOnly(): boolean;

It might be reproduced on this commit ckeditor/ckeditor4-docs@d5ddece. Seems it may be related to TS issue - microsoft/TypeScript#33939

It also means, any project using Angular integration in a similar manner as CKEditor 4 docs may have similar issues.

The workaround could be disabling some TS checks with:

"compilerOptions": {
    "skipLibCheck": true
}

in tsconfig.json file (helped in the docs case - see ckeditor/ckeditor4-docs@4ecd6f3).
