Is it possible to prevent scrolling outside the block?

There is a block with scrolling.
For example, comments on the Toaster (screenshot)

If you hover on the block and start to scroll, then when the lower boundary of this unit scrolling starts to scroll the whole page.
Is it possible to prevent scrolling the entire page until the cursor is on this unit?
Thank you.

It is possible, but unnecessary. It will add a lot of inconvenience to users.
