When I add a #load directive in order to reference an .fs file from an .fsx script file, it appears that communication with the fsautocomplete process stalls. This happens with the simplest possible files I can make, and reliably happens upon completing the line.
Repro steps
Create 'Simple.fs' as
module Simple
let times2 x = x * 2
2. Create 'test.fsx' as
```fsharp
let y = 2
Observe that type hints show in the minibuffer and help is available. Completion and tooltips appear if you continue adding to the file.
Add a line to 'test.fsx': #load "./Simple.fs"
Upon completing the line in (3), the FlyCheck modeline indicator gains an asterisk, indicating it is active
There's no big CPU or RAM consumption. Leaving it for up to 10 minutes does nothing. All FSAC functionality is gone.
Expected behavior
At the very least, I should still get FSAC functionality within the .fsx file.
Ideally, we'd get FSAC functionality for the functions in the .fs file.
Actual behavior
Hanging FlyCheck and broken intellisense.
Known workarounds
Don't use #load directives in .fsx scripts.
