[native] Address feedback from D14017

Summary: [My feedback](https://phab.comm.dev/D14017?id=46033#inline-78813) was not addressed.

Test Plan: I have not tested this. It's ultimately @angelika's responsibility to test her work, and it's unusual that a reviewer would be submitting a diff to address their own feedback
