This version is a hotfix to publish [#7743](https://github.com/swc-project/swc/pull/7743), which fixes a bug in the SWC minifier dropping **used** properties. This patch only applies to arguments of `new` calls because other related bugs are fixed by [v1.3.72](https://github.com/swc-project/swc/blob/5afdd2ed54d6097c7dfb57285a89d6ca88dbfe1f/CHANGELOG.md#1372---2023-07-28).

Sorry for the inconvenience. We are trying to find a way to verify the new optimization rules of the SWC minifier before publishing, but we don't know the way to verify it without the help of companies that has lots of application code.
