The bug for Wither Skeletons 'dancing' / flailing their arms exists in Minecraft PC 1.11.2 . This can actually be provoked in methods involving the Wither Skeletons attacking entities other than the player, and hence can be performed in Creative Mode.
I have tried four methods to provoke said bug, with interesting results. Sorry if the video quality is poor, Hypercam isn't the best, and note the cake in the videos posted below was added for humor and does not relate to the bug (On a side note not pertaining to the bug, Wither Skeletons 'dancing' in the prescence of cake would be a hilarious feature).
Method One: Cage: https://www.youtube.com/watch?v=rJOIGXwX-UA
Method Two: Spawn in Slabs: https://www.youtube.com/watch?v=dR3N52G_Kko
Methods Three and Four: Minecarts and Boats: https://www.youtube.com/watch?v=-OORhTyEA1M
So the idea here is to cage up an Iron Golem and spawn Wither Skeletons in different fashions. Methods three and four using Boats and Minecarts will have the Wither Skeleton 'dance' indefinitely so as long as the Iron Golem stays alive and they stay in their boat or minecart. Simple and easy to replicate.
Methods one and two are a bit more interesting. Method one involves caging up an Wither Skeleton with an opening door consisting of End Rods and Sticky Pistons, and putting an Iron Golem in another cage, right across within viewing distance of the Wither Skeleton.
Method two involves spawning Wither Skeletons in slabs as seen in the video above while the Iron Golem is caged.
The interesting thing about methods one and two is the Wither Skeletons will 'dance' for an undetermined/random amount of time if left alone until the World (And I say this for a reason) itself corrects itself and the Wither Skeletons stop 'dancing' and outright try to attack the Iron Golem.
It seems when the World corrects itself on this matter, any more Wither Skeletons spawned in will immediately try to attack the iron golem as normal and will not 'dance' and the glitch can no longer be performed with methods one and two in that world again, meaning if a player would want to recreate the glitch using methods one or two, they would have to create a new world to do it again.
Alternatively, The world may correct itself sooner with methods one and two if the player either bumps the Wither Skeleton, or completely destroys the structure the Wither Skeleton was spawned in.

Looking at the other case/ticket since this was marked as a 'Duplicate' of MC-87093, methods one and two that I shared are not. and do apply some potential new insight into this.
The reason why I state this is because said bug from the methods used can happen during day or night, not only in the morning as reported in MC-87093.
Also keeping in mind that with methods one and two that I tried, they act this way for a random duration until the world corrects itself in PC MC 1.11.2 and disallows this to happen again in that world, where to experience it again, the player would have to create a new world and setup the same variables for methods 1 and 2 to have the glitch happen again.
So something is happening with the world itself that is fixing it in a random amount of time with certain methods, that the Wither Skeleton's pathfinding is fixed and they no longer glitch out and outright attack. It has nothing to do with the sunlight.
This aspect may play new insight into the glitch of the Wither Skeleton acting this way, which could be important down the road to fixing it and/or working it into a potential feature in some regard.
An update on this glitch/bug since Minecraft PC version 1.12 was released. I tried to replicate the random aspects of the 1.11.2 variant of the glitches for methods one and two and in 1.12, the glitches as it was in versions before 1.11.2 is reliant on sunlight again.

Method Two: Spawn in Slabs:https://www.youtube.com/watch?v=jL3UEU1-AGs&t=10s
Methods Three and Four: Minecarts and Boats (Same as version 1.11.2): https://www.youtube.com/watch?v=OCaDNvslPro
So the randomness of methods one and two as reported above are specific to Minecraft PC version 1.11.2 only and are not related to any other version. However the main glitch with the sunlight being part of the glitch and the Wither Skeleton flailing it's arms still exists in Minecraft PC 1.12.
