This is one problem but it causes two main issues. I'm adding both of them to the same issue as they share fix.
When the user opens a modal they can scroll the hidden page behind it. This can be confusing when the user no longer recognises where they are, or know what they did to cause the change.
In iOS. When a modal has "internal scroll", when all content don't fit on the screen, it can be hard to scroll down on touchscreens. If the modal is in top position and the user scrolls up, the scroll-event will move to the next scrollable element above. When the user then scrolls down without lifting the finger the same element will receive the scroll-event.
It is very common, depending on how the user "attacks" the screen, that they will accidentally scroll a few pixels up. This means that they will be unable to scroll down in modals. They will instead scroll the page behind it.
