RequestServer hangs with high cpu usage

[warpdesign]

Summary

When opening https://www.leboncoin.fr/ad/ventes_immobilieres/2841066095 in latest ladybird build, after the initial display, the webpage hangs. The browser does not crash but it doesn't respond anymore (got the busy pointer).

Checking the Activity Monitor, I noticed the RequestServer was using lots of CPU: 99%.

Operating system

macOS

Steps to reproduce

1. run ./Meta/ladybird.sh run ladybird https://www.leboncoin.fr/ad/ventes_immobilieres/2841066095

Expected behavior

The page should load and be responsive.

Actual behavior

After a 2-3 secs, the browser does not respond anymore: mouse cursor stays busy. Even the browser chrome does not respond.
