If a sufficiently long text in an HTML tag leads to a text wrap, the calculated values (y and width) of getBoundingClientRect for characters or words directly after the wrap are not correct, if the element or one of a parent is contenteditable="true" the y value has the value as if it were still before the break the width value spans the entire width, Here a code that reproduces this failure: https://stackblitz.com/edit/vitejs-vite-jwghts?file=src%2Fmain.ts,src%2FcalcLetterRects.ts,src%2Fstyle.css
