Resolution Note:
The test is working as intended.
The singleton is being reinitialized whenever it is not present in its static variable, which will only happen after a domain reload. When running an editmode test, no domain reload will happen, unless needed. Thus the singleton from the previous run still exists.
A recommend solution could be to do a TearDown in the test, which destroys the singleton, as cleanup.
