Frame Drop Issue on Web Platform in Cocos Creator 3.8.3 or Later Versions

While developing a web client using Cocos Creator version 3.8.4, I discovered intermittent frame drops during execution.
Although the reproduction video shows that the issue occurs at similar intervals, the actual occurrences are irregular. Additionally, the frame drops persist throughout the execution rather than happening only once.

Is there a solution to this issue?

I have noticed it as well with my project after upgrading from 3.7.1 to 3.8.5.
