<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Plugins: Clean up `uninstall_plugins` option during database upgrade.
`register_uninstall_hook()` is designed to be given a function callback (or a static class variable), not an array/object instance. This got blocked in <a href="https://core.trac.wordpress.org/changeset/16339">[16339]</a> but the option itself was never cleaned up.
Props polevaultweb.
Fixes <a href="https://core.trac.wordpress.org/ticket/31625">#31625</a>.</pre>
