Table insertion fires insertElement before moving cursor inside itself

[Dylan Fitzgerald]

Steps to reproduce

1. Add an insertElement listener to the editor that performs actions at the current cursor position (example code attached; you can just dump it into your browser JS console)
2. Use the UI to add a table
3. Observe cursor position in table cell A1

Expected result

The listener's action should be performed with the cursor inside the table, where it's presented to the user.

Actual result

The listener's action is performed at the location where the cursor was prior to table insertion.

Other details (browser, OS, CKEditor version, installed plugins)

I've verified this in the CKE nightly at ​http://nightly.ckeditor.com/16-04-13-06-07/standard/samples/ using FF 45.0.2 and Chrome 49.0.2623.112 (64-bit), both on MacOS X 10.11.4.

This results from the workaround to fix #7959.

Cf. ​https://github.com/ckeditor/ckeditor-dev/blob/c1fc9a9a2c1ee7cfebab01948cd1ed77ffdef5b3/plugins/table/dialogs/table.js#L235 in which the cursor is moved using a callback via setTimeout().
