           Summary: contenteditable + getBoundingClientRect() does not
                    return the correct result
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

>From https://developer.apple.com/forums/thread/761853:

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
