Preserving Link When Replacing the Image of an Image Block within Unsynced Patterns

[prayforsurf0]

This may not in fact be a bug, but it seems to be an unusual design if it is of deliberate design...

When an unsynced pattern is created containing an image block with a link associated to where clicking said image should take the user, whenever that pattern is again used in future instances, replacing the image erases the link that was originally connected to that image.

I feel there should be a way to replace the image within the unsynced pattern, without losing the hyperlink quality associated with the placeholder image in the image block.
