Button's inner text is ignored when label exists, even though aria-hidden is set to true

Heyho,
I have the problem that a button component has a label which has aria-hidden="true" causes findByRole to not look at the button's inner text.
In case I remove the for attribute from the label, it works as expected. But according to the accessibility tab in the browser, the label is ignored even with the for attribute set.

• @testing-library/dom version: ^8.20.0
• DOM Environment:
  @testing-library/cypress: ^9.0.0
  cypress: ^12.3.0

Relevant code or config:

[
    'button1', // The correct for attribute pointing to the button, this causes the last finyByRole to fail
    undefined, // Don't set this attribute
].forEach((labelFor) =>
    it('should find button', () => {
        cy.mount(
            <div className="SCFormControl">
                {/* The label is needed due to some internal layout, other controls always have a label containing the user-visible text */}
                <label id="button1_label" htmlFor={labelFor} aria-hidden="true"></label>
                <button type="button" id="button1">
                    <span className="somestylingclasses">Button 1</span>
                </button>
            </div>,
        );
        cy.findByText('Button 1').should('exist');
        cy.findByRole('button').should('exist');
        cy.findByRole('button', { name: 'Button 1' }).should('exist');
    }),
);

What happened:

Reproduction:

See attached code snippet

Start by running the attached Cypress reproduction with @testing-library/dom 8.20.0 and compare findByRole behavior when the label's for attribute is present or absent. Trace the accessible-name handling used by findByRole; done means the button is found by the visible name "Button 1" even when the aria-hidden label references it.
