Bug 261316

Description:
fast/animation/request-animation-frame-throttling-detached-iframe.html

The test was consistently passing.  Ventura release wk1 began fail in range https://commits.webkit.org/compare/264776@main...264774@main .  Ventura release wk2 arm64 began to fail in range https://commits.webkit.org/compare/259505@main...259498@main .  Monterey release wk1 x86_64 began to fail in range https://commits.webkit.org/compare/264914@main...264911@main . 

On the bots that the test is failing it is a constant failure.  On the bots that it is passing it is constantly passing.

This issue can be reproduced on bot212 using the command: 
run-webkit-tests --no-build --release --dump-render-tree --debug-rwt-logging --no-retry-failures fast/animation/request-animation-frame-throttling-detached-iframe.html
