@gordthompson Thank you for the fix you provided! Your pr is fixing the issue you mentioned.
However, it caused a failure in our test lab which I had added the repro code as a test in this pr. Please have a look and test it. I will then go ahead and accept this pull request. Thanks again!

@v-afrafi Thanks for the follow-up. Your RegressionTest worked fine for me once I tweaked the DROP TABLE to run under SQL_2014. Using your test as an example I then added SelectIntoUpdateCountTest to verify the results of my original modification. Hope this helps.

@gordthompson awesome! good catch.
Can you just move the new test under the same Regression class? Thank you.

Done.
