If a very long link preview conflicts with the bottom slider, there is no way to scroll horizontally.

Load the attached file which should be wider than your screen.
Now attempt to scroll horizontally by grabbing the bottom slider with the mouse.
As the very long link preview conflicts with the bottom slider, there is no way to scroll horizontally.
One might think "just use the arrow keys then". Well e.g., some sites do other things with the arrow keys already, so that is not always an option.
It seems to me if the user is trying to access the bottom slider, the link preview should go away while the mouse is there.
