Reapplies PR #59492
See #59492 (comment)
Bisecting two years ago ( #47101 (comment) ) shows this regression was introduced in b2d54d9 in 2021. Somehow this hasn't been patched since then.
PR #48313 was supposed to address this, but the PR was closed and never merged and the bug has persisted.

arr == x
withnp.equals()
which will handle broadcasting in most cases by itself. For the remainder of cases, an explicit type check is done to return an array for the mask.doc/source/whatsnew/vX.X.X.rst
file if fixing a bug or adding a new feature.Has a KNOWN test failure of
