Issue: Canvas.drawImageNine incorrect edge case
Labels: framework,has reproducible steps,P2,team-engine,triaged-engine,found in release: 3.22,found in release: 3.23

### Steps to reproduce

run the attached code, it will call `Canvas.drawImageNine` 7 times, each case contains two images: the left one is the result of calling `Canvas.drawImageNine` while the right image shows how the `center` parameter is positioned within input `ui.Image`

### Expected results

i would expect the case 6 (the one with the red "center" rectangle) to be similar like the case 2 (only reversed / mirrored)

### Actual results

the case 6 is the same as cases 1 and 7 where the "center" rectangle is invalid (it is not completely within the image bounds), also i would like to know if the way the image is drawn in those two cases is correct since the official docs don't mention how to deal with the incorrect "center" rect
