Artboards affect pixel alignment?

[Intuos5]

Each artboard resets rulers to a 0,0 position in the top left. So even if an artboard is not pixel aligned, the ruler implies it is. The pixel grid is even shown correctly, but the vector objects on such artboards are rasterised off-pixel.

It seems logical that the pixel alignment is document wide. However, with an (accidental) off-pixel artboard position, it can be tricky to diagnose the problem if you don't know this is the case. That is because all clues — except for the artboard position, which you don't see when you don't activate the artboard tool — signal that the pixel alignment is correct.

Steps to reproduce

1. Create a new document with pixels as units (e.g. 24x24 pixels wide)
2. Create a new artboard
3. Create a shape on the artboard
4. Align the shape to be pixel perfect (e.g. X=10px, Y=10px, w=6px h=6px)
5. Go to View > View Mode > Pixel - to turn on pixel preview
6. Move the artboard position in 0.1 px increments
7. Notice how the shape is now incorrectly rasterised, despite the transform studio stating that its position is pixel perfect.

Expected result

The Pixel view could resets the rasterisation to be aligned with the artboard's internal origin for each artboard when the artboards are not touching/ overlapping.

Or, show a message warning message (a yellow triangle like in the pre-flight panel) on the artboard name when the artboard is not aligned to the pixel grid.

This would be quite useful for a lot of problems with Pixel work.
