Should be polyfilled for now, until it has normal support?
// @ts-expect-error This does not exist outside of polyfill which this is doing
if (typeof Promise.withResolvers === 'undefined') {
if (window)
// @ts-expect-error This does not exist outside of polyfill which this is doing
window.Promise.withResolvers = function () {
let resolve, reject
const promise = new Promise((res, rej) => {
resolve = res
reject = rej
})
return { promise, resolve, reject }
};

it has normal support?
It already has, supported by every browser, also supported by Node - but we need to upgrade to LTS Node version 22.
Also: We already polyfill this for Nextcloud server, so the only problem here are the tests.
Image preloading should be rate limited, to not overload the server. Now it is set to max. 5 requests at the same time. Signed-off-by: Ferdinand Thiessen <opensource@fthiessen.de>
