QtWebEngine continuously allocates memory until it is terminated. I tried disabling the GPU, but that had no effect.

To be able to reproduce this behavior I used a webpage (see attachement webpage.tar.gz) which loads a svg using a XMLHttpRequest every 100ms.
I used the simplebrowser example and Arch Linux Qt 6.10.0 build for this test. I also tried the Falkon browser, with the same result.

At the beginning the memory footprint looked like this:

After about 35 minutes it looked like this:

To verify whether this was a Chromium issue, I ran the same test with Chromium (141) on the same system, but Chromium did not show any memory leak.
