Screenshot of the network tab that shows that the browser is stuck loading a css file

Hello,

Here are the steps to reproduce:


1. Go to https://disneycruise.disney.go.com
2. Execute the following code in the console
window.addEventListener('pagehide', async () => {
    const r = await fetch(location.href);
    console.log(r);
});
3. Click on "Sign in or Create an Account", this is in the header close to the search bar on the top right.
This should open a new page "https://disneycruise.disney.go.com/en/login?appRedirect=%2F
but here the browser will start requesting the document of the page and few other resources but stays stuck
while requesting "https://cdn3.parksmedia.wdprapps.disney.com/media/profile-spa/1.6.0-184/styles.7e26e406cfcd02d2aa32.css".
After this, the browser refuses to load this URL "https://cdn3.parksmedia.wdprapps.disney.com/media/profile-spa/1.6.0-184/styles.7e26e406cfcd02d2aa32.css"
even in new tabs, even in new windows, accessing this URL makes the browser stuck loading it. And the only solution
is to close the browser and re-open to be able to access "https://cdn3.parksmedia.wdprapps.disney.com/media/profile-spa/1.6.0-184/styles.7e26e406cfcd02d2aa32.css" again.
