editor#resize event should pass dimensions in data

[Olek Nowodziński]

At the moment, there's no simple way to save editor dimensions (those passed to editor.resize()) when user resizes the editor. It also means that there's no way to restore them, i.e. if user re-visits the page.

Following the ​question on SO.

Changes and tests in ​branch:t/11905. Also reported #12357.

Use cases:

• rezise by code.
• resize by user interface (right bottom handler).
• maximize plugin.
• window resize while CKEditor is maximized.
• collapse / expand toolbar.

• you commented out two assertions: ​https://github.com/cksource/ckeditor-dev/blob/9a795fbfb37388a2dbcb8a126854d6b9ee25ea9a/tests/plugins/maximize/maximize.js#L61-L70 they should be removed or used,
• please prepare manual test which allows to resize, delete and recreate editor to check if recreated editor has the same height as deleted.
• properties you added to the documentation need descriptions: ​https://github.com/cksource/ckeditor-dev/commit/7d70614b69482b112a44f3f2833f82ba86846e2b

Replying to pjasiun:

• you commented out two assertions: ​https://github.com/cksource/ckeditor-dev/blob/9a795fbfb37388a2dbcb8a126854d6b9ee25ea9a/tests/plugins/maximize/maximize.js#L61-L70 they should be removed or used,

I commented them because they fails, they are new ones. I reported ticket:12357 for them as well. I don't see nothing wrong here. But instead of adding commented assersions I could also create a ticket branch #12357 and put them there.

• Finish button in the manual test does not work, because 1.js file does not contain bender.test method. If manual test contains testName.js file it is the automatic part of the test which will be run when manual part of the test is done (this is why manual test with testName.js has Finish button instead of Pass). If you just want to execute some javascript in your tests put it in the HTML file or create _assets folder.
• do not use localStorage in your test, every test should be independent, use variable instead,
• move manual test to the resize plugin folder.
