@stencil/core/screenshots type definitions missing (> 2.4.0)

Since @stencil/core version greater than 2.4.0 the .d.ts fiels of core/screenshots are missing.
This is still the case in version 2.6.0.

I know that the screenshot API is not stable, but I don’t expect missing type definitions as an intended change, therefore I am reporting this as a bug.

As i am using something like

import { ScreenshotConnector } from '@stencil/core/screenshot';

class CustomScreenshotConnector extends ScreenshotConnector {
...

i need to revert to older versions to keep using custom screenshot connectors, as the typings cannot be found.

Any chance those types will be included in the next versions?
