Nether portal particles accumulate while the game is running in background

When there is a Nether portal in the game's field of view and Minecraft is placed in the background for a period of time, a huge amount of particle effects will appear when entering the game again.

Steps to reproduce:

1. Open a world and ensure that there is a portal in sight.
2. Put Minecraft in the background and wait for a while.
3. Re enter Minecraft and you will see the scene shown in the attached video.

This seems to be a long-standing issue, such as MCPE-61085.And this may also exist in other particle effects.
