Summary:
Before this change, in case of incorrect measurements, Fabric's implementation of `measure` and `measureInWindow` incorrectly returned negative height and width. Now it returns zeros (as classic React Native does).
Fabric:
This does not fix `measureLayout` called for virtual nodes. This is not so trivially to fix and it will be done separately.
Changelog: [Internal] Fabric-specific internal change.
