Minecraft Java Map indicator not moving while in the nether

So I made a locator map while in the Overworld assuming that while the map will look the same, the indicator will still move around while I'm in the Nether. I know this works on Minecraft Bedrock but I am on Minecraft Java and I am wondering if this is either a bug or I am doing something wrong or a feature of Java edition.

It's a feature of Java Edition. Options of navigation in the Nether are very purposefully severely crippled. Maps contain white noise, compasses go crazy, and most certainly the maps from other dimensions don't show your location in the Nether. I'm actually surprised Bedrock Edition violates this rule, because it's quite fundamental to the concept of the Nether. It used to lead to situations where players would be lost in the Nether for hours, and forced to commit suicide to return to the overworld.

1.16 is the first update that ever-so-slightly decreases this difficulty with introduction of Lodestones, Respawn Anchors and Ruined Portals allowing some navigation and ability to work up the resources to escaping the Nether even after losing the original portal.
