"RetainOmniboxOnFocus" feature is used instead Related Chromium change: https://source.chromium.org/chromium/chromium/src/+/46147680fe334aeec900ec6d76c8b9e443d07452 Adds flag-guarded support for retaining omnibox on focus. This CL adds flag-guarded support for retaining omnibox contents on focus (as opposed to clearing it). When enabled, omnibox contents will also be fully selected (to allow for quick replace) and zero-prefixed suggestions are still shown (to allow for quick search). When enabled, only devices with large screens, attached keyboards, and attached precision pointers are affected.
