The expected looks buggy. It's hard to tell what is causing the jumpiness of the slider values. I'm planning on adding a change threshold to the slider when there are discrete values to snap to. The slider will not update the value if the threshold is not met. I think a reasonable threshold is one slider value away. This may help with what's happening here.

I think a better approach might be to have a preview area of the text size and hold off updating the preference until drag end.
