Issue Description

I am experiencing a problem with... F8 (run selected code) not doing anything. Restarting the PowerShell session resolves this issue. Not sure why this happens. But I'm pretty sure it's related to #2627 as usually at this point any autocomplete doesn't work.

At the same time F5 works as required.
