Revert "MyDash: restore compatibility with 3.14 and 3.14.1 after previous
commit."

I'm going to reapply the workaround in a different way to support extensions
interoperability.

This reverts commit 8d2ccc73b79a483126bd1b23e6fe0de356dd7c73.
MyDash: rework workaround for compatibility with 3.14 and 3.14.1.

This way improve other extensions interoperability, as the method is not copied
and pasted anymore.
