Do not hide new adding window for rotated transient launch

The hide operation is mainly used to avoid showing navigation bar
with inconsistent rotation after recents activity switches to next
app. So if the state stays at running recents, let the adding
windows show normally.

Bug: 302249163
Test: Disable home rotation. Launch landscape app.
      Enter recents. Long press power key.
      The power menu should be visible.
