After Grid, put within viewport doesn't work without changing the window first

After Grid, put within viewport doesn't work without changing the window first.

After using the grid plugin to move/resize a window, the put plugin's 'put within viewport' only temporarily puts the window where it should go, then the window goes back to where it started instead of staying in the new place. If the window gets moved or resized the put plugin's 'put within viewport' goes back to working.

I've tried it with both the mouse and keyboard shortcuts with the same results.
