Sub-menu goes Offscreen where there is a lot of links

Having this problem on multiple projects, I decided to make a patch that reduces the height of the submenu enough to fit inside the screen and then add a scroll on it.

Thanks for flagging this.
This is particularly irritating for Views
which is at the bottom of the Structure menu
I can see just 9 of 24 items.
I would prefer to see the sub menu placed higher alongside its parent as well as having a scrollbar as it is not easy see the list when you scroll down a small 'listbox'.

I made a second version of the patch.
So first if the sub menu goes off screen, it changes the position of it to the top of administration menu. If this is not enough to fit inside the screen adds the scroll and readjust the height of it.
