Send Mail from Ticket without scrollbar

Hi,

we are using the "Send Mail" function from inside tickets a lot. If the mail message gets longer or the browser window is not so big it is impossible to send the mail as the button is outside the window. Either the textfield nor the complete window is showing a scrollbar. 
I think it would be best to display a scroolbar in this case.

I have tested it with version 11.2.2 and 11.2.3.
