But when a char input, the new char will show in the new line. I think new char has show in the right positoin but the cursor does not show right. Reproducible: Always Steps to Reproduce: 1.input any characters 2.spacebar to the the last column of that row 3.cursor will appear at the last characters input. 4.input a charecter, that char will appear in another position(not at the last character that cursor are standing). Actual Results: can not determine where did the cursor move to

It's nothing to do with keyboard navigation. is the text area using fixed-width font? also it depends on the word-wrap behavior. I don't think it's a bug.
