Unified file view while split is selected


At the following page

https://github.com/laravel/laravel/compare/5.2...8.x?diff=split (files changed tab)

Split view is enabled, however only the first few files respect this setting, everything after is displayed as unified

Shortly after posting this it started working properly,

I still had the browser tab with it being displayed incorrectly open so I took a screenshot

Seems to only be the case while logged out, if Im logged in to github the split view does not have this behaviour
