We already have code that avoids moving the frame on hittests that are read-only. Was this really necessary in trunk to fix this bug?

While this patch is still an optimization. It makes it impossible to improve the :active handling to for instance stop showing :active if the finger moves off the target.

:active is used to show the user what is activated, but once the finger ends off the target this link will no longer be activated, and thus the :active feedback to user will be wrong.
