Tested and validated in a disco VM which had chromium-browser installed (but not the chromium snap). I dist-upgraded to eoan, and chromium-browser was upgraded to 77.0.3865.120-0ubuntu1~snap1. I verified that the chromium snap was correctly installed, but the password-manager-service wasn't connected. I then enabled eoan-proposed, updated chromium-browser to 77.0.3865.120-0ubuntu1.19.10.1, and verified that the password-manager-service was connected.
