Button "Toggle Quad View" and hotkey Ctrl+Alt+Q work very strange. This operation does not restore perspective view back.
Expected behaviour like in Maya where space used for this operation.
1. Fresh Blender started. Default cube visible. Under butoon "Toggle Quad View" Lock option **checked.**
2. Press Ctrl+Alt+Q, viewport split to 4 views - Top, Camera, Front and Right.
3. Hover mouse cursor over Top view, press Ctrl+Alt+Q.
- Result: Camera view expanded back.
- Expectation: Top view should have been expanded.
1. Fresh Blender started. Default cube visible. Under butoon "Toggle Quad View" Lock option **unchecked.**
2. Press Ctrl+Alt+Q, viewport split to 4 views - Top, Camera, Front and Right.
3. Hover mouse cursor over Top view, press Ctrl+Alt+Q.
4. Looks like all works, Top view expanded like expected.
5. Hover mouse cursor over Top view, press Ctrl+Alt+Q.
- Result: Quad view restored, but Camera view (top right) was replaced with Top view.
- Expectation:Quad view restored with Camera view on its place
- Expectation: Top view should have been expanded
