I see that you updated the docstring in recent commits. Thanks!

(Side note: Is there a way to track commits related to a bug report? I
saw this change by sheer luck.)

Then, there is a bug in `string-pixel-width':

string-pixel-width is an autoloaded and natively compiled function
defined in subr-x.el.

Documentation
Return the width of STRING in pixels.

(string-pixel-width "asd") ;=> 30
(string-pixel-width (propertize "asd" 'line-prefix "123")) ;=> 60
