... by the removal of the preview feature which was working fine. The publish feature was indeed a bit suboptimal but the preview feature was great and working fine for years. This is a big step towards making MediaWiki editing less awesome for people who do not want or cannot use parsoid. I guess this is a sign of a lost perspective and for defying reality.

True. This isn't cool.
Missing the preview feature as well!
Is there any way to reactivate the preview?
I am both saddened and highly annoyed. The feature was one of the most used on my wiki.
This functionality has been moved to a gadget by Hydra/Gamepedia contributors. See this page for download and instructions. Note that the Gadgets extension is a requirement. Works at least for MW 1.31.x.
Thanks to @FreedomFighterSparrow: for detecting this and sharing the info.
As of the time of this comment, there seems to be an intention to bring this functionality back, starting version 1.39, as obvious from the mentioning of a configuration variables in Extension:WikiEditor#Realtime_Preview
