Ok, so... where did it go?
Mass just does not dissappear
Even if it vaporized it still has mass in the form of vapor. You can still see SOMETHING following the trajectory after it passes the sun
I expect it was torn to shreds, but where did those shreds go?
If some of them got sucked into the sun I would expect the remaining debri not to follow the original path (it would have changed trajectory outward as it lost mass inward)
