Description

Run: http://tests.ckeditor.dev:1030/tests/plugins/enter/list One of tests throw:

Discontiguous selection is not supported. selection.js:1974
CKEDITOR.dom.selection.selectRanges selection.js:1974
CKEDITOR.dom.range.select selection.js:1014
CKEDITOR.plugins.enterkey.enterBlock plugin.js:392
enter plugin.js:525
editor.addCommand.exec plugin.js:13
exec command.js:52
CKEDITOR.tools.extend.execCommand editor.js:825

Tests pass, but we're apparently trying to do something incorrect.

Changes in branch:t/12257. Simply when there is added range into relection while already exists one Chrome shows warning. To prevent this situation we have to clean reanges before adding one. In git:ce84cc4 I added wrapper function (this commit is optional).

This patch is incorrect and tests very quickly prove that. You should run tests related to the change on at least Chrome, Firefox and one of IEs before putting a branch on review.

The reason why this patch is incorrect is that Firefox handles multi-range selections, so it's not correct to remove all ranges between adding a new one.

The thing that we must check is why selectRanges( ) is called with multiple ranges in http://tests.ckeditor.dev:1030/tests/plugins/enter/list, because it doesn't seem to make sense.

Note - selection.removeAllRanges() is called at the beginning of selection.selectRanges(), so if only one range was passed, then there's no chance of creating the discontiguous selection.

It turns out that this issue was fixed by #12630. So there really was some reason deep under the ground.
