The feature logic itself was only enabled for embedded tasks, but the styling change could not be limited in the same way and was applied to every task view. Advanced Form Tasks render their form inside a separate, isolated container so that they can support additional custom controls. For these forms, the new display layer sat on top of the form, creating an invisible overlay that captur
