Always run a complete switch workspace handler on navigation end (inPreview)

Needed to ensure all windows belong to the space's workspace. Especially this
case:

- Start navigating (from A) to the previous workspace (B).
- Drag and drop a window (X) from B to A
- Navigate back to A and end navigation.

X still belongs to B unless the full event handler run.

ref commit: Ensure all windows in the space belong to the workspace before completing workspace switch
