This is making things worse for us, for example:

src/...test.tsx:271:15 - error TS2554: Expected 2-3 arguments, but got 1.

271     userEvent.click(screen.getByLabelText(/only show changes/i));
                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  node_modules/@testing-library/user-event/dist/click.d.ts:1:37
    1 export function click(element: any, init: any, { skipHover, clickCount }?: {
                                          ~~~~~~~~~
    An argument for 'init' was not provided.

Same issue for hover, unhover, dblClick, and more.
TargetElement used to be exported but not anymore.

@nstepien Thanks for the report.
Rollup removed the types from lib.dom.d.ts 🤦

[ph-fritsche]

@nstepien Could you have a look at #599 ?

[ph-fritsche]

Check out v13.0.4 🚀

[riboher]

Hi there! Issue with exporting TargetElement is still happening after updating to v13.0.7 😞 . Typescript is complaining about TargetElement not being exported in @testing-library/user-event

[ph-fritsche]

@riboher Yes, TargetElement is completely removed.
It was Element | Window and used in multiple places, where the actual typings were different. It won't come back.

What have you been using it for?

[riboher]

Oh! Ok! Good to know then. Just needed it for typing one of my tests and make sure a nextSibling was correctly typed for an upload event. You say I can try with Element then? Thanks!
