while bumping from tslib 2.4.1 to 2.5.3 our CI blocked PRs because more than 3kb Size increase in our bundled code.
I did some amount of investigation and it looks like there is increased occurrence of Object.create; statements emitted within the bundle that don't do anything . This looks like cause of __assign helper from tslib.
if we bump only to 2.5.0 the regression does not occur.
