Customer Impact
This is regression from 3.1. When people import certificate and key from a pfx file, that may not be able to use them.
The issue had repro case for adding the key to a certificate store but it can impact other scenarios as well.
This is macOS specific. Originally reported on Bug Sur 11.0 - but reproduced also on Catalina 10.15.
Testing
This bug caused relevant tests not to run and fail silently (as they check if write to a certificate store is possible before the run) I verified manually that the existing tests do run and pass as well as I verify that the repro code works on 10.15 and 11.0.
Risk
medium. The fix is not large but it creates new relation between X509Certificate and temporary storage when needed.
