The Script reference provides a link to an older version of it. For example, if you open this page: https://docs.unity3d.com/ScriptReference/AssetPostprocessor.html You see in the upper left "Version: 2019.1 (switch to 2018.4)", as shown in the image below. If I press the "2018.4" link, it does not forward to the same documentation page I had open. In this case, it does not forward to the AssetPostprocessor.html file but the "Welcome" page. Please add functionality to open the same page as opened earlier, but in the other documentation version.
