Editor: long URLs are not broken in notifications

[eliorivero]

I have Google Fonts blocked in /etc/hosts and I get this notification when I edit a post, which is fine, except by the fact that it overflows:

The attached patch solves this by allowing to break the long string and it looks like this:

Allow to break long text strings in TinyMCE notifications

Could we potentially also style these to match other core notifications, either right above the editor or inline? (Though maybe that doesn't matter so much because of Gutenberg. Pinging @joen for any thoughts there.)

We're still using TinyMCE in Gutenberg. We use it to power almost every textfield. So if this is a notification that is generated by Tiny, it'll still show up. Might be worth looping in @afraithe?

@Joen this notification is not showing up in Gutenberg.

It appears like this has been fixed in Gutenberg but still remains an issue outside of there. Is there any reason not to accept this patch and fix the remaining cases? @melchoyce

@afercia has the internal issue from TinyMCE been resolved that was mentioned in Slack?

@dmsnell I have no idea :) Best person to ask to: @azaozz I guess.

@dmsnell this was fixed upstream some time ago in TinyMCE 4.6.6, see ​https://github.com/tinymce/tinymce/blob/master/changelog.txt#L102. I can't reproduce it in trunk and 4.9, where did you see these warnings?
