Editor: the beginning of a title is not visible after tabbing from title to content area

[designsimply]

Steps to reproduce:

1. Start a new post using the Calypso Editor
2. Write out a really long title that is longer than the title field
3. Press the tab key to move into the content field

Result: the beginning of the title field isn't showing

When writing a long post name, after inserting it and hitting tab to go to content, it should scroll the title back to the beginning.

Ok to close with an explanation if it's not something we want to take the time to update.
