Affected Version: 2.13.7-3593-g6323c254ef

What steps will reproduce the problem?
1. Load an internal change like https://chrome-internal-review.googlesource.com/c/353523/?polygerrit=1.
2. Look at CQ-DEPEND lines in description.

What is the expected output?
I expected the Change-Id on the CQ-DEPEND to be linkified to point at the corresponding public issue, as happens when viewing a public change, e.g. https://chromium-review.googlesource.com/c/476111/. (Both public and private IDs are linkified there.)

What do you see instead?
No link.
