Don't reload page after clicking on Diffusion line link

Summary:
For a single line, I can use the right click.
But for highlighting multiple lines, I have to wait for page reload.

It would be nice to track this in history but that's more involved.
This is actually maybe better behavior.

Test Plan: Clicked on the line link, dragged and dropped on it.
