Editor: Instead of cutting off title, shrink the font size to fit?

[blowery]

Steps to reproduce

1. Starting at URL: wordpress.com
2. Start a new post
3. Give it a long title, enough to be longer than the available space
4. When I click out, the title is cut off and it's not obvious how to get to the rest

What I expected

To see the whole title after clicking out

What happened instead

The title was cut off

Browser / OS version

Any

We could either use a smaller font size as the title gets longer, or just use a smaller title font in general, or let titles wrap. It's really a pain on mobile, as you only have a few characters to work with and there's no way to get to the title that's off screen.
