 @westonruter

 According to my tests the wp.editor.initialize function call takes ±100ms
 to run - both on first initialisation, and on subsequent TinyMCE
 initialisations just as well.
 This seems to match the delay you experienced here with it requiring 100ms
 of 'visibility' before someone can interact with them.

 Correlation != causality... but my guess is that this is the browser's way
 to protect the computer resources by delaying any scripting that belongs
 to iframe's that are not visible.

 I would recommend hiding it with something else than display: none (maybe
 position: absolute; left: -999em; instead) ... and see whether the browser
 behaves differently and allows the scripting to take place even before the
 user interacts with it and the iframe turns into becoming visible.
