I had the same problem but made it a fixed element that on clicking the editor icon, becomes separate from the editor toolbar and places itself at suitable height from the bottom of the screen..
Works a treat for me.

Try it if you want. . .

/* Editor buttons fixed*/
.b-editor .cke_top {
    padding-right: 32px;
    position: fixed;
    top: 390px;
    z-index: 100;
}

I tried to extend it by putting the smilie and attachment buttons in there but couldn't figure that bit out. .

I use it in one style only specifically for the writing of longer text. .
