[1.5] Provide an option to keep frame when special workspace is present on hyprland

### Feature Description

Currently when a window is present on a special workspace, frame disappears and only bar becomes present.

Special workspace is opened with a window in it:

I basically want to keep the frame. It does not disappear when there is no window in the special workspace.

Special workspace is opened without a window:

### Use Case

When I open a special workspace, shell oddly changes position and I simply don't like the behavior.

No files, tests, or entry points are named. Start by locating the shell's frame behavior for Hyprland special workspaces and reproduce the two states shown in the issue; the work is done when an option preserves the frame with a window present and existing behavior remains unchanged when it is absent.
