Lisp exception when deleting a line: repaint-inferiors-pass-2-sr: adjusting items that should have been handled in pass-1

Repro steps

I reproed this with Boxer 3.4.19 2024-06-24.

1. Download, unzip, and open layout exception repro.box.zip
2. Delete the line labeled "b" (so that the box is reduced from 3 lines to 2 lines)

Unexpected result: A Common Lisp exception is thrown:

Lisp Error:repaint-inferiors-pass-2-sr adjusting items that should have been handled in pass-1
  inf-screen-obj: #<screen-box 1 >
  (screen-obj-x-offset inf-screen-obj): 4
                          inf-x-offset: 5
  (screen-obj-y-offset inf-screen-obj): 0
                          inf-y-offset: 0 

I'm not sure how I created this box that reproduces the issue. I started hitting this issue in a more complicated project and was able to simplify it down to the repro I've shared here.

I've changed this from an error form to a log:error form so any issues get logged, but it doesn't crash. So far, on reproducable instances I've seen of this, it's usually a small desprepency, like a pixel or so based on the font styling calculations.
This will be included in 3.4.22. Thanks for this very reproducable test case @rigdern
