Comment (by SergeyBiryukov):

 In [changeset:"57673" 57673]:
 {{{
 #!CommitTicketReference repository="" revision="57673"
 Tests: Use `assertSame()` in `wp_read_image_metadata()` tests.

 This ensures that not only the return values match the expected results,
 but also that their type is the same.

 Going forward, stricter type checking by using `assertSame()` should
 generally be preferred to `assertEquals()` where appropriate, to make the
 tests more reliable.

 Follow-up to [49/tests], [198/tests], [34374], [48937], [52269].

 Props costdev.
 See #59655.
