Is divergent blade trap still not registering hits at high quality (inc. rotation speed)?

I saw a report and testing of this in jungroan's blade trap champion video.

He reports that there is some server communication issue or some reason why divergent blade trap above 25% quality is not registering hits due to rotation speed being too high.

I cannot find information on google, and the bug reports search for this issue yields 1000 pages of results. (query: blade trap rotation speed)

~~Can anyone tell me if this bug is still in the game, so i can know if i can add quality to my gems?~~
