a weird little promise wrapper around playwright event

eventPromise.ts

export async function blockUntilEvent(page: Page, callback: (frame: Frame, resolve: any, reject: any) => Promise<void>) {
    return await new Promise((resolve, reject) =>
        page.on('framenavigated', async (frame) => {
            try {
                await callback(frame, resolve, reject);
            } catch (err) {
                reject(err);
            }
        })
    );
}
