无法为任何发现添加书签

Question

我有一个场景：

我需要在搜索结果上悬停，一旦悬停，书签符号可见，只有这样我才可以在书签标记上添加书签

    Wait Until Page Contains Element xpath=.//*[@id='content']/div/div/div[2]/div[1]
    Mouse Over xpath=.//*[@id='content']/div/div/div[2]/div[1]
    Wait Until Page Contains Element xpath=(.//div[@class='bookmarkPanel'])[1]
    Click Element xpath=(.//div[@class='bookmarkPanel'])[1]

错误：元素不可见
