No marker next to module
See attachment. Types get a fixture marker, but modules do not.
This seems OK to work for me in VS Mac 18.104.22.1689 (d15-5). Might be doing something wrong. The only problem I can see is that methods in the module are not shown in the Unit Tests window and if you run the tests for the project the module does not get marked green or red in the Unit Tests window and stays undefined.

Just took another look at this and you can see the issue in the files TagComments.fs and TypeSignatureHelp.fs in the F# addin test project.
I didn't notice last time, but the marker _does_ appear but then promptly disappears again for some reason (see attachment)
Can't reproduce with master:
Are you able to with the latest master ?
@Mike - I can still reproduce. I just realised that this issue only occurs when you using IExtendingTextLineMarkers. (Turn on "Show function type signatures" in F# settings)
