This is a bug and we’re looking into it. It appears to be specific to Safari on iOS (Chrome on iOS is a Safari skin); it doesn’t affect desktop browsers, Android/Chrome, or Android/Firefox, which is why we didn’t notice earlier. This most likely started with a change on desktop where clicking on a post (without modifiers) opens when you press the mouse button, rather than when you release it.
