A UI bug in the list settings component causes the input field to display “[object FocusEvent]” when clicking out of it, reported in Safari and Chrome on macOS with Discourse 2.9.0.beta6. hierocles first identified the issue, which was reproducible on a fresh install. MarcP initially couldn’t reproduce it but later confirmed it on commit 201228162c. The issue was traced to a recent change in the value-list component, with hierocles noting it didn’t occur in an earlier commit. The bug was ultimately fixed in pull request #17389 by cvx.
For any list-based setting (not sure what the Ember terminology is), there is a bug where clicking the input box and then clicking out of it will replace the contents with “[object FocusEvent]”. This occurs in Safari and Chrome (running on macOS) on a clean install of 2.9.0.beta6 with no plugins. No errors are reported in the logs or any messages in the browser console.
Steps to reproduce (this can be reproduced anywhere using a similar list setting component)
