PowerShell Intellisense and most right-click feature stop working

[messy17]

Issue Type: Bug

When I author PowerShell scripts, I notice that after a non-deterministic amount of time, Intellisense for the cmdlets stops working. When this happens, the "PowerShell" progress message spins indefinitely. What else happens is that most of the right-click functions such as Go to references or Go to definition do not work. A blue progress-like indicator starts scrolling from the left to right across the top of the screen. The only way to fix this is to close VSC completely (reloading the extension of VSC does not resolve the issue). I first noticed this behavior two releases ago.
