Actually there were two independent problems
1: continue would jump to the starting point of the label, instead of
the continue-point of the labelled loop.
2: A for-initializer with no awaits in the for would still get its
variables hoisted, so
label: for(var i = 1; i < 10; i++) {continue label};
would transform to:
label: {
i = 1
for(; i < 10; i++) {continue label;}
}
And that fails.
