[FF] Browser uses default cursor for inline editors

[Piotrek Koszuliński]

1. Open ​http://ckeditor4.t/ckeditor/samples/inlineall.html
2. Try editing any contenteditable.

There should be text cursor instead.

Created branch t/9222.

I'm not sure why on FF default cursor is shown (because over simple content editable element it's correct 'text'), but this fix helps. It also fixes cursor for control elements like textarea and inputs on all other browsers (except IEs which by default render default cursor).

Let's have it fixed in editable.js instead, to avoid duplicating for each types of editable: _source/plugins/wysiwygarea/plugin.js#L1279

But fixes for inline and framed editor are different. One for inline editor has to be prefixed with editor's class and added once per host page, when the one for framed editor has to be appended to the iframe's body and once per each editor. If we had more than 3 similar cases, then ok, but in this case we need two different solutions.

Garry's right that these rules are specific for all editables, so it'd be better to keep them there.

[Piotrek Koszuliński]

Currently only small improvement was possible - the cursor fix is done by editable.js. Better solution needs deep changes in adding CSS, so it would be possible to do this after editor creation.

Fixed on master. Before masterising I expanded this fix for divarea, which previously hasn't been included.
