User-defined Module name gets colorized as blue when used to qualify a computation expression name

[cartermp]

0. Using the Roslyn editor on dev15prerel with .NET Desktop installed
1. Clone FSharpx.Extras
2. Change build targets of projects if they don't load, I just changed them to .NET Framework 4.6.1 and everything was fine
3. Run paket.bootstrapper and then paket restore
4. Open Lens.fs and go to line 58, noting that State.state is colorized blue, as if it were a keyword.

However, the module State is user-defined:

I'm not actually sure what the expected behavior here should be. Should the module be colorized at all as, say, teal? Should the name of the user-defined computation expression be colorized? cc @dsyme @Pilchie

please make sure that state (the one in lower case keeps be highlighted as keyword.

@cartermp I wonder if that repros in Preview 5 (before rolsyn). No colorization logic was changed with RC?

@OmarTawfik I can try tomorrow, but this does have your type colorization work ('T and 'State are colorized in the second screenshot).

@OmarTawfik There's no coloring on dev14 Update 3 (No VFPT):

So this is a bug. As far as resolution goes, if it's not a lot of work, then I think getting state colorized as @forki requests would be best. However if that seems like it's significant work, I think we should just replicate dev145 behavior and track colorizing computation expressions at the call site as up-for-grabs.

In VS 2017 RC with VFPT installed it looks OK:
