rsleevi@ - Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks...!!

I tested some versions I could access.

52.0.2743.83 (64-bit) Hang without Rendering.
51.0.2704.84 (64-bit) Hang after rendering top portion of page.
50.0.2661.75 (64-bit) and earlier renders page entirely no hanging.

It appears the issue showed up between 50.0.2661.75 and 51.0.2704.84

There's no way this CL is related. Assigning back for triage - suspect the bisect stopping there was entirely unrelated, and may be worth bisecting again

spenson66@ - Thanks for more clarification...!!

krajshree@, or can someone please attach an HTML file? I pasted the symbols to an HTML file but does not reproduce.

The pastebin.com URL can reproduce the hang on Chrome and on Edge, but then I'll need to download the whole page and try to minimize by removing all the UI parts.

A minimum HTML file is greatly appreciated.

Probably a dup of issue 749319, but hard to be sure without minimizing.

Visiting the page at URL: https://steamcommunity.com/groups/cheatgiveaways from comment #3 reproduced the issue i.e the page crashed.

Thanks...!!

Hello,

I have attempted to use a website copier to get the HTML File, please let me know if this is satisfactory.

#13, #14, #15: Thank you all for the help, if it occurs only when "word-wrap: break-word", this is the same one as issue 749319.

kojii@ Seems I can't view 749319, is it private in some form? Would like to track it since I'm using an electron app that is also vulnerable to this due to electron being based on Chromium.

Thanks!

#17: issue 749319 was once accidentally marked as security issue, but then cleared. I'm not sure if I can open it, I'll ask around.

Thank you for the background, I'm working on a fix and the current WIP no longer hangs up your HTML file attached to #15, hopefully it's not too far to land the fix. I'll make sure the fix is recorded to this issue too.

#18: Thanks for the info! Here my electron ticket where I intend to update when the fix is landed: https://github.com/electron/electron/issues/10332 (would have replied earlier but DB issues with monorail 👀)

#18 yea, I tried to add more info to this ticket but monorail :P

Anyways I have reported it to discordapp as well as they are using the same version of chromium.

Fix mid-word-break to handle grapheme clusters

This patch fixes the mid-word-break logic, used by a few CSS properties:
- 'word-wrap: break-word'
- 'word-break: break-word'
- 'word-break: break-all'
to handle grapheme clusters correctly. Before this patch, it only
supported surrogate pairs.

The fix uses LazyLineBreakIterator and NonSharedCharacterBreakIterator
to detect grapheme cluster boundaries. Also adds tests/DCHECK to ensure
NextBreakOpportunity() returns the end of the input string if no more
break opportunities were found.
