I've added the following css rules to the esoui+ stylesheet:

td.vBulletin_editor .controlbar textarea,
td.vBulletin_editor .controlbar iframe {
    width: 100% !important;
    height: 100% !important;
}

td.vBulletin_editor .controlbar textarea {
    resize: none;
}

td.vBulletin_editor .controlbar iframe[style$=" 0px;"] {
    width: 0px !important;
    height: 0px !important;
}

td.vBulletin_editor td.controlbar:nth-child(1),
td.vBulletin_editor > div.controlbar:not([id]) > div:first-child {
    min-width: 300px;
    min-height: 150px;
    height: 250px;
    display: block;
    resize: both;
    overflow: hidden;
    padding: 4px;
}

td.vBulletin_editor td.controlbar:nth-child(1) {
    width: 1000px;
}
