[Bug]: interceptedRequest.respond hangs the browser until worker timeout

[DurandA]

Minimal, reproducible example

import puppeteer from "@cloudflare/puppeteer";

interface Env {
    MYBROWSER: Fetcher;
}

export default {
    async fetch(request, env): Promise<Response> {
        const browser = await puppeteer.launch(env.MYBROWSER);

        const page = await browser.newPage();

        await page.setRequestInterception(true);
        page.on('request', (interceptedRequest) => {
            if (interceptedRequest.isInterceptResolutionHandled()) return;
            if (interceptedRequest.url().endsWith('.png'))
                interceptedRequest.respond({
                    status: 200,
                    contentType: 'image/png',
                    body: Buffer.from('iVBORw0KGgoAAAANSUhEUgAAADAAAAAlAQAAAAAsYlcCAAAACklEQVR4AWMYBQABAwABRUEDtQAAAABJRU5ErkJggg==', 'base64')
                });
            else interceptedRequest.continue();
        });

        await page.goto('https://google.com');
        let img = (await page.screenshot()) as Buffer;
        await browser.close();

        return new Response(img, {
            headers: {
                "content-type": "image/jpeg",
            },
        });
    },
} satisfies ExportedHandler<Env>;
