Yeah, and doing that, it looks like the ways you stop being hidden are attacking, casting a spell, making a sound louder than a whisper, and a creature “finding you,” which is undefined, except that the creature can find you by succeeding at a Wisdom (Perception) check with a DC equal to the total on your Dexterity (Stealth) check. So, yeah, I do think these rules are clearer now, and that clarity backs up my interpretation of the previous rules that once hidden, you remain hidden even if you stop being covered or concealed, as long as you don’t attack, cast a spell, or make too much noise, until an enemy makes and passes a Perception check.
