Bug 2044409 - Filter slider updates while Accessibility shouldUseAutoSize is false

Commit Body

The engine code doesn't allow setting a fontSizeFactor when auto-sizing is enabled. We previously tried to disable the Slider that updates the size factor in order to prevent update messages, but the disable doesn't take effect until next recomposition. As a result we see crashes in monkey testing which adds noise even if it is highly unlikely for a normal user to hit.
