Nothing in this bug points to the specific call that triggered the sync reflow, so it's difficult to say for sure if the code still exists. I tried to reproduce locally by calling alert() or confirm() in the devtools console. In profiles I saw multiple sync reflows, but none of them had a stack similar to the one reported here.
