This is a follow-up to [36604]. When processing dependencies `$this->group` will be the minimum of the script's registered group and all preceding siblings. This is wrong because only a scripts ancestors in the dependency chain should affect where it is loaded. Effectively `$this->group` introduced a form of global state which potentially corrupted the group of dependencies. Sorting covers up this problem. The issue in #35873 was that script were not moving their dependencies to a lower group when necessary. The fix: * In `WP_Dependencies::all_deps()` pass the new `$group` value to `WP_Dependencies::all_deps()`. Previously the wrong value was passed because the parent script could have moved with `WP_Scripts::set_group()`. * In `WP_Scripts::all_deps()` pass the `$group` parameter to `WP_Dependencies::all_deps()` so it doesn't always use `false` for `$group`. Same for `WP_Styles::all_deps()`. Props stephenharris, gitlost. Fixes #35956.
