A span-tag at the end of a paragraph, e.g: <p>Text <span></span></p> Does not have a proper offsetLeft when there is a whitespace between the text and span-tag.

Created attachment 461375 [details] Safari 15.6 differs from other browsers I am able to reproduce this bug based on attached test case and Safari show extra line (Expected offsetLeft for empty span-tag...), which is not present in other browsers as can be seen from attached screenshot. I am changing "bug" status to NEW. Thanks!
