[psychedelicious]

Summary

• When using save-as with filter/select-object, do not exit the filter/select-object. This facilitates common workflows that want to use the output of these features for multiple layers.
• Fix a bug that is exacerbated by this change that causes inpaint mask and regional guidance layers not rendering correctly.
