Issue description

Not working abort link when choosing/clicking the PayPal-Button as payment method. I am using the Web-Drop-In in a Capacitor Angular app.

I am currently testing a Braintree (PayPal) checkout in sandbox mode. I initialize the drop-in with the following options:

const options = {
  authorization: {token},
  container: '#dropin-container',
  locale: 'de_DE',
  paymentOptionPriority: ['paypal'],
  card: false,
  paypal: {
    flow: 'checkout',
    amount: {price},
    currency: 'EUR',
  },
  translations: {
    chooseAnotherWayToPay: 'Anderen Paypal-Account verwenden.',
  }
};

When the PayPal-Popup opens where I should enter my PayPal-Account-Credentials there are different ways to close the popup.
At least on iOS are appearing 2 options. The first option is the popup (modal) closing cross in the upper right corner.
The second option is an abort link "Cancel and go back to {company name}" below the login form.

When using the cross in the upper right corner the modal closes successfully. I expected the same behavior for the abort link.

I am wondering why this abort/cancel link is only appearing on ios (safari) and not on Android (or Chrome). And when I hit the link instead of the cross - the cancel process fails, I get asked if I want to try this again, which does not work too and the popup tells me immediately after this second attempt that I was too long inactive.

I usually expect anywhere the same behavior, Chrome should show the same as Safari.
Maybe there is a way to forcefully hide this abort link?

I already asked the same thing Braintree via GitHub, unfortunately without success.
