stockyo827@, what's the app you are using to show this issue? Is that possible for you to provide a sample app to demonstrate the issue?

The app looks like some email app, if so, could you please send us (webviewteam [at] gmail.com) a copy of that?

Did you see this issue with other devices? Which is the latest version of WebView you see it rendered correctly?

Hi ctzsm,

Yes, it's an email app, we render user's email on Android app, and email contents from our server's email service provided by html format.
I will think how to provide a sample app for you.

I've tried other devices as below, all devices are update chrome to latest version on google play:

Represented failed on: Samsung S8+, Samsung S7 edge, Samsung SM-N910C, Huawei 9P, Sony Xperize XZ, Xiomi 6, Nexus 5X
Represented passed on: Google Nexus 6P, Sony Xperia M4, Nokia 6

And all failed devices if I uninstall updates on chrome to roll back factory version, they works passed.

I don't know which latest version rendered correctly, because only I can try is update to latest version on google play or remove update to roll back factory version. Or can you teach me how to get other version of chrome app?
If you can, I would test others to find latest version which worked fine.

Thank you for providing more feedback. Adding the requester to the cc list.

stockyo827@, thank you for providing more info!

If you could provide us a sample app, we probably could bisect this issue (find the least good build). It looks like a regression, but we need a way to repro this issue so we could process, thanks!

Hi ctzsm,

I've provided a sample app as attachment.
Please reproduce the issue by this sample app, hope to help you find root cause, thanks.

Using the per-revision bisect providing the bisect results,
Good Build - 63.0.3239.150 (508578)
Bad Build - 64.0.3240.0 (508892)

Please navigate to below link for log's and video--

Unable to provide the per-revision bisect as the application gets crashed when application is launched using the builds invoked. Observed the same even after increasing the range.

@aluo -- Could you please look into this issue and provide the pre-revision bisect. 

Thanks!

Assigning to aluo for per-cl bisect. If not possible, please pass back.

battun@, could you please help to bisect this?  See comment 7 for device and Android version.

chaopeng@  Might be it looks like this issue is related to your change. please look into once, if its not related to your change please reassign back to me. 

Thansk!

Hi stockyo827, I can reproduce your issue with your app.
But I can not reproduce it with the html file https://bugs.chromium.org/p/chromium/issues/attachmentText?aid=329426 with another test Webview app.

I also seeing an issue in your sample:

<meta name="viewport" content="width=device-width; initial-scale=0.75; user-scalable=1;">

viewport meta should use , not ;. So please tried with:

<meta name="viewport" content="width=device-width, initial-scale=0.75, user-scalable=1">

The CL in #10 is aimed to give a correct fallback if page give a invalid value.

Forgot to mention:
The app I use: https://play.google.com/store/apps/details?id=com.snc.test.webview2
The test link: http://ht.chaopeng.me/word-break.html

chaopeng@,
Although it is not recent regression, since now we have 'per-cl bisect, marking  as RBS for now for tracking. Next week is Stable cut, so if we can get the fix before that, it would be great.

Thanks!

Hi chaopeng

I had removed ";" on my sample code as attachment.
And the word-break still not work.
The test step and result still as Comment 2.

Thanks.

stockyo827@ could you please try https://play.google.com/store/apps/details?id=com.snc.test.webview2 see if your issue is causing by any webview settings.

If you can please also share the webview app source with me.

Hi chaopeng

I had shared webview app source as attachment on Comment 15.

And I had tried the app: 
https://play.google.com/store/apps/details?id=com.snc.test.webview2
And input this url:
http://ht.chaopeng.me/word-break.html

The word-break works fine.

In your attachment, I saw you still using ;

width=device-width; initial-scale=0.75; user-scalable=1

please replace all.

I can reproduce your issue on https://play.google.com/store/apps/details?id=com.snc.test.webview2 when toggle all settings same as your app. And it can fix by correcting all ,

See #11

Hi chaopeng

Sorry I didn't notice that.
I had corrected all ";" to "," then word-break works fine on my sample app.

So, should the bug fix by ourself that replace ";" to ","?
Or my webview's setting was wrong?

Yes, the issue is because you don't use correct syntax for viewport meta.
