The undecorated child migration creates a synthetic decorator, which contained `"exportAs": ["exportName"]` as obtained from the metadata of the parent class. This is a problem, as `exportAs` needs to specified as a comma-separated string instead of an array. This commit fixes the bug by transforming the array of export names back to a comma-separated string. PR Close #34014
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
