Cannot compose a new email in Yahoo Mail when using an iPhone user agent string and WebKit r178097 or later. In particular, a JavaScript TypeError is thrown after clicking on the compose button.

On a Mac, you can reproduce this issue by performing the following:
1. Open Safari with WebKit r178097 or later.
2. Open a new window.
4. Ensure the Develop menu is enabled (*) and choose Develop > User Agent > Safari iOS 8.1 - iPhone.
5. Navigate to mail.yahoo.com and sign in.
5. Click the compose button.

A JavaScript TypeError is thrown and caught by Yahoo Mail's code as indicated by the presence of the following line in the Web Inspector console:

"Error Reported (presentModalView): Type error"

(*) You can enable the Develop menu by choosing Safari > Preferences to open the Safari preferences window. In the preferences window, click Advanced in the toolbar. Then check the checkbox "Show Develop menu in menu bar".
