Issue descriptionSteps to reproduce the problem: 1. Open any site having an element with fixed position from the bottom of the window or screen 2. Scroll down till the address bar disappers 3. Scroll up to show the address bar 4. Notice that the fixed element is jumping This happens only in IOS 11 Chrome, and working fine in IOS 10, all android chrome browsers and even in Safari IOS 11 Please refer the attached screen shot for better understanding What is the expected behavior? Looks like the page/screen height is recalculated dynamically to 100% in both the cases, with address bar and without address bar. What went wrong? The page/screen height is dynamically recalculating, causing the fixed elements of a site to change position. Did this work before? N/A Chrome version: 61.0.3163.100 Channel: stable OS Version: Chrome 62 Flash Version: This is working in previous IOS chrome version IOS 10 and below

I'm sorry, but I can't tell exactly what is going on just from your screenshot. Do you have a test page, or a video of this bug reproducing? When the user scrolls and the toolbar is shown/hidden, the webview's frame is continuously updated during that interaction, meaning that the page's viewport size is continuously updated. Is this what you mean by "dynamically recalculating?"

This is fixed by the smooth scrolling workaround, which will start rolling out to users in M71.
