Dash doesn't support line editing at all out of the box, though you can
build it using libedit.

Not a lot, really. If the display engine assumes that the only characters
on the screen are the ones it writes there, and the terminal emulator
violates that on a screen size change, you're basically left with running
^L (with or without a numeric argument to restrict it to the current line)
a lot.

Now, if you force a complete refresh with ^L and the display is still
wrong, we have a redisplay bug.
