Masayuki-san, please CC our developers on the maildev mailing list. This is an important subject to avoid editor regressions in Thunderbird. Jörg. -- Sent with FairEmail for Android https://email.faircode.eu Jan 24, 2020 09:21:53 Masayuki Nakano <mnakano.birchill@mozilla.com>: Hi, I updated the sheet [https://docs.google.com/spreadsheets/d/19hj6utJC08rRlkGkqOj5hLY5Gi6jRACdXqOQVJPzk8o/edit?usp=sharing] to make it clearer whether each editor API is tested simply or not. The coverage is still really low even though some of them are used in mozilla-central... I'll keep increasing the coverage when I have time, but most of them are not used in mozilla-central. So, I really want contribution from comm-central staff. -- Masayuki Nakano (Birchill) <mnakano.birchill@mozilla.com> [mailto:mnakano.birchill@mozilla.com] Working on DOM, Events, editor and IME handling for Gecko
