Thanks for doing this! I had considered pushing for a test in the previous PR but due to the sporadic nature, I was concerned about blocking on the PR for perfection when the fix itself was needed. |

This adds a test to check for regressions in selecting the correct workspace when there are nested workspaces.
#10846 solved a problem with nested workspace resolution that was caused by #10776. @ehuss suggested that a test should be added to ensure that this issue does not pop up again.
I ensured that this worked by testing against commit before #10846. Sporadically I would get an error that was the same as described in #10846.
I then tested it on the commit with the fix and the test passed every time.
While this does add a test to catch any regression I am worried that it will not catch it every time. It was noted in #10846 that this error would sometimes happen but not every time, in my testing I found this to be true as well. Since this is caused by the
HashMaporder changing each run, switching to something ordered likeBTreeMapshould catch any regressions every run (if the implementation were to ever change). I'm not sure if this is necessary so I figured I would note the concern here.
