Image tiling bug

I have a base image:
image
I put a image widget in a canvas penal, set and set this image in brush ,set “draw as” to “box”, “margin” to “0.33, 0.0”, I got this :
image
Then I set “draw as” to “image” and “tiling” to “Horizontal”, then set “draw as” back to “box”, I got this :
image

This means what setting draw as image affected draw as box, this should be a bug.Even if this is intention, the tiling effect is not displayed correctly

I want area A to be the beginning of the picture, area C to be the end, and area B to be tiled, so that no matter how long the picture I need can be satisfied
image
But current version can’t do it because this bug, I have to change my design

No one care about this?
