The eraser cannot function properly in scenes with PencilBrush and background images

[wangqingbang-austin]

When I use the PencilBrush component to draw marker content, the eraser does not work properly.

and the background image, even if erasable: false is set, will still be erased by the eraser.

Here is my code：

This repo is all about erasing.
I don't see any eraser components in your code.

This is my code.

When using an eraser, the pencil brush did not erase it, but the background image was erased.

Hard to understand what is expected and what is actual.
Please describe, add visuals andd a live repro on codesandbox

anyways make sure you set the pencil brush result to be erasable
