GDrive link (MP4 58MB): https://drive.google.com/open?id=12BQM_jwW4fmStyrPaaOamJeF2hnXmNIZ While using URL http://chromium.clients.arcfield.com/mobile/ As you can see, after replacing the page's content with HTML via document.write() at ~00:00:20, the page scrolls (but not all the way) yet panning left to right is unavailable.

In Chrome 56, panning works and scrolling goes all the way to the top and bottom of the page after the document.write().

Tested the issue in Android and able to reproduce the issue. Steps Followed: 1. Launched the Chrome Browser. 2. Navigated to the URL: http://chromium.clients.arcfield.com/mobile/ 3. Zoom-in to the screen. 4. Tap on the button "Replace HTML from Ajax". 5. Try to move the screen by swiping on the screen. 6. Observed that screen is not accessed normally and complete screen is not accessed. Chrome versions tested: 57.0.2944.0, 63.0.3239.83(Stable), 65.0.3292.0(Canary) OS: Android 8.0.0 Android Devices: Pixel XL Build/OPR1.170623 Using the per-revision bisect providing the bisect results, Good build: 57.0.2943.0(436483) Bad build: 57.0.2944.0(436816) You are looking for a change made after 436494(GOOD), but before 436495(BAD). CHANGELOG URL: The script might not always return single CL as suspect as some perf builds might get missing due to failure. https://chromium.googlesource.com/chromium/src/+/22a14115b5adb0df9540eaf1afb273a3f8dd6baf From the CL above, assigning the issue to the owner concerned. @bokan: Could you please look into the issue, pardon me if it has nothing to do with your changes and if possible please assign it to owner concerned.
