Hi Team,

While going through Blink's commit, I came across this nasty bug where the test case make Safari do continuous reload and cause issue. I think it is good to fix it right away.

Test Case with continuous reloading - https://jsfiddle.net/v960ryzt/

^ in Safari 16.2 & STP161, it will continuously reload scrollbar while it does not in Chrome Canary 111 and Firefox Nightly 111. It seems like that the navigation is stuck and page is refreshing.

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/3ad81cf0b724a2a25ee5cc79a09541d9a971ae15

WebKit Source - https://searchfox.org/wubkat/source/Source/WebCore/loader/FrameLoader.cpp#2739

I just wanted to raise bug so we can fix it.

Thanks!
