// rebaselining when all platforms are supported.

// 1. Run a CQ+1 dry run.
// 2. Click the failing bots for android, windows, mac, and linux.
// 3. Find the failing interactive_ui_browsertests step.
// 4. Click the "Deterministic failure" link for the failing test case.
// 5. Copy the "Actual pixels" data url and paste into browser.
// 6. Save the image into your chromium checkout in content/test/data/forms/.
