Even DevTools doesn't pop up a keyboard when you type. That has a significant effect on the page and fails to present a realistic expectation.

I agree—no tool, including DevTools, simulates the on-screen keyboard and its impact on the viewport. Mobile View is still a tool—for a quick preview of the responsive design and presentation (to a client/employer), not a full emulator for final testing.

For a truly accurate test (keyboard, touch, performance), you still need a real phone—this is stated on the website and in the Chrome Web Store description. But as an idea for future implementation, it's excellent! Thanks for the feedback; you actually dug into it and thought about what was missing)

Got bitten by it. A fixed input at the top of the screen just disappeared. Needed an entry in the page meta to sort it.

		That's a good, concrete example. This is the blind spot of preview tools. These are the kinds of bugs — viewport behavior with keyboard input, 100vh glitches — that the preview won't show at all because there's no keyboard. Now if i go for keyboard/viewport simulation, I'll know where to start looking and what will help me fix them (interactive-widget=resizes-content, etc.).
