Description

$ids = array_filter( $_POST['ids'], 'is_numeric' );

Even without wp_unslash (shouldn't report an error either)

Same when using is_int or is_float as callback

Probably fix is similar to https://github.com/WordPress/WordPress-Coding-Standards/pull/1679

Research direction

Start by reproducing the reported array_filter example with is_numeric, is_int, and is_float as callbacks, and compare the expected behavior with the approach in pull request #1679. The issue is done when these callback forms no longer produce an incorrect sanitization report, including the case without wp_unslash.
