What she said. Every time you stop because she is having a fit, she is learning that what she has to do is have a fit so you'll stop. What you want her to learn is that when she stands quietly, you will stop, and to do that, you must never stop unless/until she is standing quietly.
As she already has a bad habit, you might have to start with getting her to stand quietly while you water the ground at her feet. When she can do that, work up to standing quietly while you rinse her hooves. Once she's got that, move up to rinsing her lower legs, then her upper legs, and so forth in small stages.
