Safari: First enter does not break the line in enterMode BR + SCAYT

[tobiasz.cudnik]

Safari: First enter does not break the line in enterMode BR + SCAYT.

Reproduce

1. Don't disable SCAYT
2. Set enterMode to BR, eg in config.js:

   config.enterMode = CKEDITOR.ENTER_BR
   

3. Start with an empty editor.
4. Type "foo".
5. Hit enter.

Result

1. Nothing happens (no space).
2. Hitting second time breaks the line.
3. Typing something after first enter hit, and hitting it again (once) breaks the line correctly.

Expected

1. Carret is placed in next line.

Can't be reproduced without SCAYT enabled.

Could you please specify which version should we test? We can reproduce this problem even with SCAYT disabled on nightly build but on trunk this problem is absent!

Not a SCAYT problem, actually a DUP of #5212, where we were missing releaser update, now committed with [5515].
