fix: insert indent guides *before* .cursors

[aleclarson]

This makes the cursor(s) appear above the indent guide.

My testing shows the indent guide position is unaffected, which is good.

Oh, looks like there's some visual shifting when you scroll. Looking into it...

Alright, everything is working correctly! LGTM.

Thanks for this fix – resolved the cursor issue for me
