Revert 296279@main: Caused a page load speed regression on older iPhones
https://bugs.webkit.org/show_bug.cgi?id=295726
rdar://154856800
Unreviewed revert of a perf regression.
296279@main moved intersection observations into a queued task instead of
executing
the callback synchronously when the intersection was observed. This seems to
have caused
a page load speed regression on some sites in PLT on older iPhones. Reverting
for now.
