Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0 Steps to reproduce the problem: 1. create a very long line of text without spaces (eg 80k characters) 2. duplicate the above line 3. in the duplicated line insert any tag which should not normally interrupt the continuity of the text What is the expected behavior? The two lines should be of equal length when viewed in the browser What went wrong? The lines are of different length, text positioning starts failing immediate after the tag, resulting of different text line lengths Did this work before? N/A Does this work in other browsers? Yes Chrome version: 63.0.3239.108 (Official Build) (64-bit) Channel: stable OS Version: 10.0 Flash Version: Shockwave Flash 27.0 r0

Chrome Channels where this issue is reproducible : Stable, Beta , Dev and Canary. Does this reproducible on older versions of Chrome stable : Yes(M62,M61 and M60 still need to bisect) Note : . -Other browsers works fine I see this behavior only on Chrome.

Note, this flag is no longer present in the official Chrome/Chromium.

Able to reproduce the issue on reported chrome version 63.0.3239.108 and on the latest canary 65.0.3297.0 using windows 10, Ubuntu 14.04 and Mac 10.13.1. As the issue is seen from M(50) 50.0.2661.0 considering it as non-regression and marking it as Untriaged.

Looks like a layout issue.

I suspect we hit the TextNode max length. |
