surface: don't early return when clearing hyperlinks (#3033)

When outside the viewport, other actions such as scrolling might be
happening, and doing an early return when clearing hyperlinks prevents
scrolling upwards.

We reposition the check, and do not early return so we can process
scrolling when it happens.

This fixes #2645, restoring the ability to scroll upwards while
retaining the behavior of hyperlinks when outside the viewport.
