Steps to reproduce: 1. Bring up a web servert that would just hang on requests to http://127.0.0.1/slow.html 2. Navigate to a page with the following content: ``` <body> <script> let i = 1; const print = () => { document.body.textContent = ('raf #' + i); console.log('raf #' + i); i++; if (i === 5) { location.href = 'http://127.0.0.1/slow.html'; } requestAnimationFrame(print); } print(); </script> </body> ``` Expected: page keeps running rAF's before new navigation is committed. Actual: rAF's stop soon after provisional navigation is started. Note: this has to do with libwpe/wpebackend-fdo. It worked with libwpe-1.8.0/wpebackend-fdo-1.8.0 and stopped working after switching the deps to libwpe-1.14.0/wpebackend-fdo-1.14.0.

It seems that it regressed somewhere between wpebackend-fdo 1.8.0 (good) and 1.8.4 (broken).

Ok, I pinpointed it to https://github.com/Igalia/WPEBackend-fdo/compare/1.8.2...1.8.3 which is basically this commit: https://github.com/Igalia/WPEBackend-fdo/commit/1a4fd5f0ac3d759867301e7b7366f71e2a501630 @aperez can you have a look?
