[MC-250209] scoreboard.dat filling with dead entities

In our world there are many entites given scores and killed by our datapack. The bug happens when a already dead entity gets assigned a score. The entries in scoreboard.dat are not removed and will stay there indefinetely causing the file to grow huge in a matter of hours. This results in Auto-Save times of about a minute after a day of playing and us having to delete the file itself resetting all scoreboards.

An example datapack is attached

Could you create a minimum viable test case, so this can be verified and the cause properly identified?

Thank you for adding the datapack. 🙂
Can you also provide information on how to use it, with consistent steps to reproduce the issue? Such as; any commands to use, functions to run, and in what order.

Still happens on version 1.20.4, can be reproduced as follows:

Create a world using the attached datapack.

Run "scoreboard objectives add foo dummy".
Run "scoreboard players list", the number of tracked entities increases every tick.

Have reproduced on both Ubuntu and Windows.
