The sendkey/xtype command can't return email/sender result list which inputed (roundcube mail)

I use sendkey or xtype command in searchbox

There isn’t the result such as in which in image

Here is my command: https://drive.google.com/open?id=1AGdImAWc88_-QfrqOK0n7S8EMrUHz05U

Here is the searchbox code. My webmail uses roundcube mail
roundcube_searchbox_code

Please help me! Thank you very much!!!

What exactly goes wrong? UI.Vision enters the correct word, or?

But if the target of sendkeys was filled id=quicksearchbox, the keyword search (Research@msb.com.vn) is deleted. Therefore, there aren’t the results as the 2nd image

Thanks for your reply!
