Another chapter in the Storied Annals of Weird `in_array()` Behavior:
`in_array( 4, array( "4-cool-dudes" ) );` resolves to `true`, such that
`is_page( 4 )` was returning true for posts with the name `'4-cool-dudes'`.
We work around this behavior by ensuring that values passed to the `is_`
methods are cast to strings before the `in_array()` checks. ID checks still
work as expected; see #24674.
