TRAVIS_COMMIT and TRAVIS_PULL_REQUEST_SHA commit SHA's getting masked in web log output

I have a CI job in which I’m logging the TRAVIS_COMMIT and TRAVIS_PULL_REQUEST_SHA environment variables. However, when I view the log output in Travis’s web console, these two log lines (and only these two) show up as two strings of 76 asterisks:

****************************************************************************

It looks like one of the automatic secrets-masking processes is being overly aggressive (here is one of them). Is there any way I can have my log output include these commit SHA’s?

Thanks,
