In order to run this test against React >=17, you should include // @reactVersion >= 17.0
pragma above the test definition

Stack:
Summary
Closes #28960
In #28467, we started reading context values by advancing a cursor in the context dependency list. However, in React 17, multiple reads of the same context are only tracked as a single dependency so we don't know if we should advance or not. Keep in mind that the passed
context
should be ignored in later versions of React where the real context object may not be available (e.g. inuseFormStatus
).So for React 17 and below we just completely fallback to the old approach of reading the current value from the context object. In those versions
useFormStatus
doesn't exist.How did you test this change?
