We have a page that appears to have been broken with the latest chrome update (to 84). There's a checkbox with an onclick event, that no longer fires. We're presented with an error: Uncaught TypeError: timeline.toggleWatcher is not a function

attached is the HTML calling this JavaScript function

```
<ul class="dropdown-menu dropdown-menu-right condensed-dropdown">
                    <li>
                        <a class="pos-rel" data-watcher-toggle-type="submitter" data-notify="submitter" data-selected="true" onclick="timeline.toggleWatcher('submitter')">
                        <span class="dropdown-toggle-icon">
                            <i class="fa fw fa-check-square"></i> 
                        </span>
                        <span class="history-filter-label">Submitter</span> </a>
                    </li>

                    <li>
                        <a class="pos-rel" data-watcher-toggle-type="watcher" data-notify="watcher" data-selected="true" onclick="timeline.toggleWatcher('watcher')">
                        <span class="dropdown-toggle-icon">
                            <i class="fa fw fa-check-square"></i>

                    </li>
                </ul>

Has timeline become a reserved word in JavaScript?
