Preview window no longer update simulation when running on 4.25

mini-viewport (preview window) disappears in 4.25 when running a simulation but it works in 4.24
any help to figure out why this is happening will be appreciated. thank you

[screenshot from 4.24] showing the selected compsure layer stays visible and active during a simulation run.

it seems that Epic Games fixed that issue in 4.26. problem solved
