Problem: When you level up, ONLY the square icon for spring attack is shown, and ONLY the active portion of spring attack shows on hover over mouse pop up text.
In other words, someone new to the game would assume THAT IS ALL spring attack does, because the game does NOT tell you about the passive benefits unless you take the square feat and the later check your char feat page.
People leveling up only see the spring forward clicky and maybe don't know what they missing.
