Query Results don't render - later appear in another tab incorrectly

Node.js: 10.2.0
V8: 6.6.346.32
OS: Windows_NT x64 6.1.7601

Steps to Reproduce:

1. Open two queries in separate files such as:
   SELECT 'Query1' AS Query1, GETDATE() AS Stamp
   and
   SELECT 'Query3' AS Query3, GETDATE() AS Stamp
2. Run each using same connection
3. Eventually one of them fails to render results
   • not sure why or how to repeat 100%
   • appears to being long running but profile shows completed
   • cancel doesn't do anything
4. Now close and reopen the same files and run with same connection.
5. Boom - get mix of results from execution in step Update CONTRIBUTING.md #3.
   • notice date stamps appear as though data did come back properly step#3
   • notice column names and row results are from different executions.

I will post a gif in a bit.

@joshbooker thanks for the GIF! That really helps understand the issue better.

More info: the behavior starts by looking like a like a long running query - Run btn disabled, Cancel does nothing, no results ever render - sometimes the the execution timer is still running but Profiler shows successful completion. Disconnect and change connect works, but the weird part is when you close the file and open another file and execute with same connection. You get rows from current execute in columns from prior execution. It's like the results that never rendered before are rendered now except in columns from current exec. It gets really funky when the column counts don't match.

The results never rendering is common but the only way I can repeat the funky results is when I reopen a file.

@kburtram You're welcome - spent half day on this repro and issue post...high hopes you'll fix asap so I can stop reverting to SSMS ;).

I was unable to repro this with the latest code on master.

@aaomidi This is still happening for me:

Same repro steps. Trick is to get one query to 'hang' somehow(?) - that query appears to run 'Executing query...' status indefinitely with timer running forever. Then close and reopen a different .sql file and execute to get the 'hung' query results in the other query pane. The only way I can repro this is after closing and reopening a .sql file from disk.

Thank you! Will look into this again!

Has anyone been able to reproduce this? Still plagues me daily.
