#wait_while_present will do a #reset! (remove the cache of the driver
object) and attempt to locate the element from scratch with the selector
`{class: "here"}`. If it finds it, then the wait loop will continue, if it
does not find it, it will exit out of the waiting loop.
Incidentally, I think I've found a way to make that the default behavior
for `wait_until(&:present?)` so I might be deprecating
`#wait_while_present` and `#wait_until_present` entirely to minimize this
confusion.
