Created attachment 381852 [details] Screenshot with notes for observing bug on the page document.caretRangeFromPoint returns incorrect range for some google docs documents Steps to reproduce: 1. Open https://docs.google.com/document/d/1G0PhdEEVO1BTzRHZipnksOci4eIWyXEevPvHL5rlNxM/edit?usp=sharing 2. Set browser window width to 1490 (not necessary but helps with exact coordinates sync) 3. Open developer tools 4. Call document.caretRangeFromPoint(595.265625, 293) -- it's coordinates of first letter of word 'general' in the 4th line of the doc 5. Observe returned range. Its startContainer and endContainer erroneously point to different Dom node, in this case blue underline that google docs use to imitate link on ', I am a link' text in the middle of the document Expected behavior: document.caretRangeFromPoint(595.265625, 293) returns range in textNode containing 'general' in the 4th line of the doc Notes: doc.elementFromPoint(595.265625, 293) on the other hand works just right
