4 reports are added to a dashboard and then resized to optimise the data on display and aligned so the 4 reports are of equal size, and the dashboard saved.
Reloading the dashboard, some of the reports have resized away from the alignment manually set earlier.
For instance on the demo server : load 'tablero_mando' dashboard, resize the report 'distibucion financiera' so its lower boundary is the same as 'distribucion tarjeta credito', and save and reload the dashboard : the two reports are different sizes on the dashboard.
