Issue

I found it's weird that when the footer of history item list is set to not display, there seems to be some invisible items in the list which cause several times non-functional key press when using arrow keys to select items.

Like the picture below, for example, when you are focusing on the item 'a', and you want to select item 'c', the expected behavior is just press the down key one time and the focused item will be changed to 'c', but in fact, you need to press 6 times (on my machine), just like there are some invisible items after the item 'a'.
