Searches for TypeScript features in a .ts file seem to end up in the JavaScript section of Dash.
To reproduce:
- Create file foo.ts (in, say, WebStorm):
interface Foo {
bar: string;
}
- Position the caret in
interface and press Cmd-Shift-D.
Results: searches for "javascript: interface". (And I have Node docset installed, so it finds a match there.)

Expected: should search for "typescript: interface"
