Oh, yes, I also often have that issue(although I use middle mouse click for that).

I also have these issues with Vim plugins - suddenly websites make scrolling almost unusable with an animation(which is never seen when scrolling with a mouse, touchpad etc. but seems to exist solely to annoy keyboard users), or they can't be scrolled at all, or the whole website UI is built with crazy JS magic so that the plugin can't even find a single link on the whole page.

I don't want to know how bad it must be for blind people who have to rely on automatic tools.
