[AD 2.3.1] Weird artboard behaviour

[MmmMaarten]

Not sure what is going on here, but it looks like a bug to me. When enabling the children of an artboard suddenly the bounding box of the Artboard changes and prevents us to actually change the artboard size.

[edit] Although while doing another test I'm not sure this is a bug. When starting a new artboard and drag a layer in there it looks different compared to the other artboard. The first artboard looks like a masking group, while the second is not. Still I find the behaviour as seen in the video strange as it prevents us from resizing the artboard so still doesn't look right to me. As to me it doesn't make sense that the handles of the artboard move and prevent us from sizing the artboard (which is still selected), only because it's children are getting enabled.
I'll include the affinity file in the attachment.

Please see video:
(BTW sorry for the missing part on the right, it was scaled in OBS and only now see it, but I'm toggling the layers on and off there)

I can confirm that this is not controlled or determined by the child layers of the Artboard - but it is being controlled by the Vector Mask applied to the Artboard in your document.

The behaviour you're seeing is expected, and the same can be seen with both Artboards and simple vector layers alike.

With a Vector Mask enabled, the Bounding Box and control handles shown will be limited to the Vector Mask area, regardless of the parent objects original size.

Toggling the Vector Mask visibility will 'hide' the mask and return the parent object to it's original full size, with a bounding box etc to match.

You can see this occurring in the below recording -

 

I hope this clears things up

Thanks @Dan C and for adding a video to it even. I get what you mean and show. 

Honestly I wouldn't even know why I would ever want to mask the artboard, so it was an accident that I got in that state in the first place (and I only saw later that it was actually masked).

Thanks again for the clear explanation. Makes complete sense now.
