Sorry, never mind. I had to enable js-jsx-mode to test it properly.

So, closing.

Note that you can do it yourself by appending -done to a bug email.

Start with emacs -Q, create new jsx file, paste following content:
const foo = (props) => (
    <div>
      <input
    cat={i => i} />
    </div>
);

Then put cursor after closing input part (/>) and hit <RET>. Cursor will
end rith below the "c" in "cat", but it expected to be below open
bracket "<". If I remove "{i => i}", then indentation behavior works in
an expected manner.
