Steps to reproduce

ps aux | grep powershell | grep -v grep

Expected behavior

Return filtered results. I.e. same as

PS > $a = ps aux | grep powershell; $a | grep -v grep

Actual behavior

Pipeline hanging (first grep never receives "output closed" event, besides the fact that corresponding stream is disposed)
