Stencil Version

4.14.0

Current Behavior

Following up on #5252 (comment): When using testing-library/dom with stencil errors occur when using getByRole and getByLabelText

getByRole

Right-hand side of 'instanceof' is not an object

getByLabelText:

TestingLibraryElementError: Found a label with the text of: Test, however no form control was found associated to that label. Make sure you're using the "for" attribute or "aria-labelledby" attribute correctly.

Expected Behavior

Both methods should find the respective element without errors
