Cursor disappears

I've noticed that the cursor disappears when moving back to correct something.

I have been able to fix it by editing:

`ZSH_HIGHLIGHT_HIGHLIGHTERS=(main cursor)` with `ZSH_HIGHLIGHT_HIGHLIGHTERS=(main)`

Not sure if this is the correct way to fix it but it's working now for me.

Start by reproducing the disappearing cursor with `ZSH_HIGHLIGHT_HIGHLIGHTERS=(main cursor)`, then inspect how the `cursor` highlighter handles movement and redraws. Compare the behavior with `(main)` and verify that the cursor remains visible when moving back to edit text.
