Ghosting when using Transform on a pasted layer

SUMMARY
Pasting a vector layer into an image, which is too small to have it placed in its original position, results in layer having incorrect bounding box. Using some tools displays a ghost copy of the layer contents that cannot be interacted with.

STEPS TO REPRODUCE
1. Create a document
2. Add a vector layer to it
3. Create vector polygon shape _in the lower right corner_
4. Cut or copy _the layer_
5. Create second document using "Create from Clipboard" to produce a smaller canvas OR resize the canvas of the original document so that the copied layers content is now out of its bounds
6. Paste the layer

OBSERVED RESULT
The shape is placed correctly within the visible area of the image, but using Move a layer tool on it outlines rectangle way too big and outside of images bounds (inluding part where shape used to be in the source image). Using Transform a layer or selection tool outlines area way too big and shows a ghost copy of layers conent outside of images bounds. Using Image > Trim to current layer expands the image to include this wrong bounding box though there are no actual shapes there.

EXPECTED RESULT
The bounding box on a pasted layer is expected to outline its actual content of vector shapes, regardles of whether it could be pasted at the original position or had to be moved to fit into destionation canvas bounds. No ghost visuals should produce when applying tools.
