Regression range only contains f554b1544f1c1d6a3360472366720667aa5480d2	(Reland "[d8] implement setTimeout.").

The last time we had this report ( crbug.com/734409 ), it looked very unrelated to the CL in the regression range at first, but then it turned out that we really keep too many objects alive by creating a cycle of weak global handles. That was fixed then, and the leak disappeared.

Maybe your CL also keeps something alive on the heap?
