This looks expected code size increase due to the implementation of a new feature (ES6 module,  Issue 594639 ).
The increase looks like the cumulative increase by a large part of our new implementation (At least the top ~20 of the partial symbol diff (Comment #3) are new functions, implemented by many CLs in  Issue 594639 ).

The increase is reported to be caused by my single CL probably because my CL caused the new code included in the release binary, while the code has been omitted previously because it was unreachable from HTML/JavaScript.

Makes sense, thanks for the explanation!
