So, `Text` editor can access the `Text` node quickly and it's not needed to be grabbed by a lot of transactions. Additionally, when we support keeping `TextEditor` instance even if the text control is reflowed (bug 1922141, bug 1339052 and bug 1620050), transactions need to work with new anonymous nodes. Therefore, retrieving `Text` node of `TextEditor` each time does make sense rather than storing the node. Depends on D240419 Differential Revision: https://phabricator.services.mozilla.com/D240420
