Confirmed locally. This occurs because for some reason, specifying cols="5" (which is supposed to limit each line to 5 characters) ends up limiting to 6 characters on these systems: `data:text/html,<textarea id="ta_wrapped" cols="5">hi hello my longfriend t sq t</textarea> Observe that there is a line "longfr", which is 6 characters long. It should be "longf". MDN notes that cols is specified in "average character widths". Because we're dealing with average here, I guess that could result in some edge cases. However, this seems to fail all the time for me: `data:text/html,<textarea cols="5">testing testing</textarea>` Observe "testin" instead of "testi". Emilio, you're probably not the right person to ping about this, but would you have any idea who is?
