Thanks for the Report.

could you please provide us the sample html file / URL to triage the issue further.

Hi,

I am creating a Hybrid Mobile App & i had used simple HTML 5 DataList
Control, which was showing earlier but stop working in recent Android
System Webview Update.
When i  uninstall the Webview it came back.
Following is the HTML Code for same

<input focus type="text" placeholder="City/Municipality" ng-model="dc.model.
address.MunicipalityID.label" list="municipalList" data-list-filter="^"
maxlength="100" />
            <datalist id="municipalList">
                <option ng-repeat="x1 in dc.model.MunicipalList" value="{{x1
.LookupValue}}"></option>
            </datalist>



Thanks & Regards,
Sanjay Nagpal

Any Update on this?

Hi,
I'm having the same issue as described.
You can easily test it on datalist test page - http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_datalist
(datalist is not showing up). The issue persist also on beta channel.

Alright, this is a regression between versions 54.0.2808.0 and 54.0.2809.0.

wangxianzhu@ can this be related to any of your changes in the range of CLs in comment #7?

Re #8: Unlikely.

There are two datalist related changes which might be the cause:
https://chromium.googlesource.com/chromium/src/+/f8bb8bc5b0ecb2e7d63f598b52dfadf27cd3ed19
https://chromium.googlesource.com/chromium/src/+/7b8a38bd4485221cc71355c22e86c3e4c5b2a970

Ah, thanks  wangxianzhu@ I just took a quick look at the CLs and the closest (language-wise) to data list I could find was your data item list stuff (but I guess that could be completely unrelated ;))

Tagging this as RB-Stable given that it's a regression.

hmmm, tkent@ is ooo this week :/

manually reverted those 2 changes (1 at a time), still see the datalist not showing up.  I'm having trouble building with the old tree, will work on more proper bisect Wednesday.

Alright, thanks aluo@

Found breaking cl: https://codereview.chromium.org/2007473004  This issue happens only in webview, not chrome.  Assigning to Gustav for now but cc'ed original committer as well.

OK I suppose this has the same root cause with  issue 662040 , which has been solved by https://chromium.googlesource.com/chromium/src/+/b0152a63b6a341a79949f97b8d77ea876d73727c on M55 branch, but seems it's too late to merge into M54.
For sure would you please help to confirm whether this issue still exists on latest M55? Thanks.

M55 should have been fixed, but Master is still not OK, https://codereview.chromium.org/2523193002/ is trying to do so for Master.

So sorry for the regression...

Confirmed fixed on M55 55.0.2883.64 on Nexus 6 device but not on master.

Waiting for landing of https://codereview.chromium.org/2523193002/, after that we need to merge both https://codereview.chromium.org/2491103003 and https://codereview.chromium.org/2523193002/ into M56(branch 2919).

#Note: M55 has already been fixed by https://chromium.googlesource.com/chromium/src.git/+/b0152a63b6a341a79949f97b8d77ea876d73727c, no further work needed.

Removing M55 given c#21, we'll keep the bug open to track the fix for M56.

Locally confirmed on Android device that datalist can show well on the latest M56(branch 2924), because the root cause has been solved at  issue 662040 .

Confirmed fixed on M56 56.0.2924.51 on Galaxy A5.

[Auto-generated comment by a script] We noticed that this issue is targeted for M-56; it appears the fix may have landed after branch point, meaning a merge might be required. Please confirm if a merge is required here - if so add Merge-Request-56 label, otherwise remove Merge-TBD label. Thanks.
