When using the search field in Reddit, the cursor location is off by a few spaces from what you see. Let’s say you type the word “desktop” in the Reddit search field and place your cursor between the letters “e” and “s”. The actual placement will be between “o” and “p”. If you swipe the cursor to the left from between “e” and “s” the movement/highlight will start at “o” and “p”.
This works as expected in Chrome, FF etc. And so far the only problem site is Reddit and it is 100% repeatable.
