The problem revolves around a fault in the way the plug-ins selects the context from which it heals, I found this issue specifically when using the heal selection plug-in, but it applies to others as well.
When trying to heal on a layer inside a folder, the plug-in uses the layers outside said folder instead, see example:
Selecting an area inside the folder, 10 pixels all around inwards towards center (applies in other configurations too)
Instead reconstructing the line (or similar), it fills with content from the layer outside the folder.
I don't think this is the desired behaviour, should it be that way users must be prompted with an option to change such option (GUI example below)
