phaser3 memory leak issue?

In my game there are about 250MB of resources (including images/audios…)

when play game, the memory usage continues to rise (up to 3GB…),

so I wrote a test, and repot to github:

I think this is a memory leak issue,

Has anyone else encountered this problem and how was it solved?

Are the textures still in use when you remove them?

No used.
