Redstone Dust react gone wrong

The redstone dust have a serious error on action. In my first image you can see. When the redstone dust near the target. It will switch into "line dust". It just like it near the redstone torch, lever etc. (Image 3). "Line dust" is not suppose to react on the near block which doesn't link to the dust (image 3). However, in image 2 the dust is switch into line. It can still react the near block which doesn't link to the dust. That mean the redstone dust is still "cross dust" when it near the target. It is nonsense it only turn the look and the react is still "cross dust". The scene of redstone have forget to change this into line dust when it near the target. Please fix it. It affect a lot, thank you!🙏

＊"Cross dust" which is only single dust link 4 path.
