Trades page, transactions hover with many transactions

[Kansai53]

On the Trades screen if you hover the "# transactions" column but there's a large number of transactions, the tooltip goes to the bottom of the screen and you cannot see the full list. It would be solved if the tooltip had a vertical scrollbar. Or an even better solution if possible, is for each row on that screen be expandable and so you can expand one to reveal the list of transactions below it.
