You are probably looking for a change made after 442726 (known good), but no later than 442741 (first known bad).

URGENT - PTAL ASAP.

A friendly reminder that M57 Stable is launch is coming soon! Your bug is labelled as Stable ReleaseBlock, pls make sure to land the fix and get it merged into the release branch by Monday (03/06), 5:00 PM PST in order to make into the desktop Stable final build cut. Thank you!

Know that this issue shouldn't block the release?  Remove the ReleaseBlock-Stable label or move to M58.

Thank you.

abodenha@ is looking as oshima@ is on Vacation.

malaykeshav@ can you look at this since oshima@ is OOO for the next week? Probably best to revert for now since it's only affecting 1.5x.

<input type=date> + <datalist> is not very popular.  So, IMO it would be ok to push M57 stable with this bug if the first stable refresh release will have a fix.  Of course the bug might break some web sites, and we'll be blamed for it in that case.

Rechecked this issue on Ubuntu 14.04, Chrome OS Peppy and on Nexus 5 (With Android 7.0.99/ MRA20) using chrome version 59.0.3032.0. 

Able to reproduce the issue on Ubuntu 14.04, but unable to reproduce it on Chrome OS and Android as the Calendar is displayed when clicked on other.

Updating OS information.

Thanks.!

Thank you ranjitkan@. Pls add a test case for this if we haven't already.

malaykeshav@, is there any progress here?

Revert is in CQ and should be in any minute.
Meanwhile I wanted to point out that the erroneous patch effects all chrome running on fractional scale factors. It is a UI polish bug, so reverting it only causes a slightly bad UI. 

On the other hand the Calendar picker bug only happens in minor cases where an HTML widget is instantiated from within another HTML element to replace it(such as the select menu in this case. The calendar picker replaces the select menu).

Tested the patch and only found bugs as expected from  (https://bugs.chromium.org/p/chromium/issues/detail?id=612270) which has been in stable since M52. 
Could not see any other unexpected regressions in form inputs due to this revert.

Tested with :
1) data:text/html,<input type=date list=dl1><datalist id=dl1><option>2017-03-31</option> 
2) http://www.roboform.com/filling-test-shopping-cart (similar to https://bugs.chromium.org/p/chromium/issues/detail?id=612270#c20)
3) Form inputs on https://www.w3schools.com/html/html_forms.asp
4) HTML5 input from http://www.456bereastreet.com/lab/html5-input-types/

All form inputs worked as intended with the expected UI glitch from the revert.

This bug requires manual review: Only 6 days from stable, we might already have a stable candidate build

Rechecked this on chrome version 57.0.2987.96 on Windows 10 and Ubuntu 14.04, fix is working as intended. Date picker is displayed when clicked on "other" from pull down menu.

But at the same time verified on build 59.0.3035.0 and observed that on clicking "▼" nothing happens, even the pull down menu is also not displayed. 

@malaykeshav: Request you to please take a look into it.

Adding TE-Verified for M57.

> But at the same time verified on build 59.0.3035.0 and observed that on clicking "▼" nothing happens, even the pull down menu is also not displayed. 

Looks this is a separated issue.  It's reproducible on Mac too.  I filed  Issue 699585 .
