Editor not working due to JS error related to emojis

[eliorivero]

I thought this was some kind of hiccup due to a cached js or something, but I see it again.

Using 4.2-beta1-31760

Steps:

Add new post

Result:

Editor in Visual tab is not visible. Switching to Text works but clicking Visual again doesn't. Console says:

wp-tinymce.php?c=1&ver=4109-20150310:48 Uncaught TypeError: Cannot read property 'parseEmoji' of undefined

Browser:

Only tested in Chrome 41.0.2272.89 (64-bit) on OS X 10.10.2 Haven't tested others.

It was hard to figure out a line, so I set SCRIPT_DEBUG to true and hard reloaded. Bug was gone so I couldn't find the line. I turned off SCRIPT_DEBUG thinking it will appear again but bug never appeared again.

I tested this in a fresh install and it appears only once (per installation). After you reload it's gone.

Can you try a hard refresh? I saw this last night, but after refreshing, I couldn't duplicate. May be a caching problem that didn't get busted with the beta.

(Misread the line about the hard refresh attempted). It's a fun bug :)

Unable to duplicate working off of core.svn and using grunt build to spin up a fresh build.

We've since added extra sanity checking to the TinyMCE plugin. Please re-open if you see this happening again.
