Changing the fill of the layers in a group only works as expected if a pixel layer is NOT present

Did a whole project and rely heavily on being able to select a group and change all the constituent layers fills in a single go, it's great.

However, I've discovered that if I a pixel layer is present, a massive white square gets drawn instead. Take a look at the video:

It would be great if it just ignored the pixel layers (as they're mostly they're just as preliminary sketches)

Let me know if this is a bug or intended functionality.

Thanks.
