When debugging bug 1518002, I found that nsTextEditorState doesn't check whether mTextEditor isn't destroyed. Example, nsTextEditorState::HasNonEmptyValue will be called during reflow when element has placeholder. It will call editor's function, then editor returns error due to destroyed. Since mTextEditor is recycled object, it may not be enough whether mTextEditor is nullptr.

So I guess that we should check whether editor is alive on some situations.
