Mouse click or pressing 'End' at end of line with spaces

[jonathanong]

just gonna list some bugs. these are super edge-cases and are still better than what we had before.

Looks like they're all created by clicking or keyboarding beyond the "end" of a line (i.e. a line that ends with whitespace):

• pressing End on such a line
• touch-dragging past the visual non-space end of the line
• pressing down arrow from the line above

I couldn't reproduce it by using the left/arrow keys to arrive at the same position. So all three screenshots represent the same bug. Or did you get that result somehow else?

[jonathanong]

hmm maybe. i'm not even sure how i got there. i just continuously click until i find something that's off. i'll be sure to jot down the "how" next time.

Three years later, I've looked into reproducing this again, and indeed, the behavior doesn't happen on left/right arrow navigation.

Right now the position parameter to getCaretCoordinates() is simply an index into the string which we take from selectionEnd (selectionStart isn't any better), and the library isn't aware of keyboard or mouse input.

IMO the fact that selectionStart/End don't match the displayed caret position when the caret is placed there in certain ways, is a (cross-)browser bug. I've filed the bug with Chrome.
