Sample file for bug

If an <a> tag is positioned where a horizontal scrollbar will appear, the link cannot be hovered or clicked.

Note: This only occurs on lion/mountain lion with scrollbars set to automatically hide.

Steps to reproduce:

1. Load the attached example file or go to http://jsfiddle.net/yYTJV/2/
2. Hovering or clicking on links 1-4 works fine
3. Hover over link #5 and try to click it

Results:
Hand cursor does not appear. Link is not clickable. Note that the text can be selected, but the link cannot be clicked.

I think that this is a known issue. Beth, Simon, do you know if there is previously filed bug about this?

I believe that this Radar is the same issue: <rdar://problem/10929565>

But I have not found a bugs.webkit.org equivalent.

I too am having an issue with this bug.  Very similar to OP, where I have a button that gets overlapped by the space that the scrollbar would occupy if it were visible, and both the click and the hover are lost on about half of this button.
