Provide detailed reproduction steps (if any)

1. Open editor sample and clear editor contents.
2. Create unordered list with one or two elements.

Bug has appear after #646.

It seems that restoring previous functionality shouldn't be so hard. There would be analysed only start of selection what should be the same what we have in previous versions.
Replace getSelectedElement() with getStartElement() here: https://github.com/ckeditor/ckeditor-dev/blob/da389f9f08a8df4562ce14ae02ad215dd510c454/plugins/stylescombo/plugin.js#L145

But still entire menu seems to be a little bit buggy.
In case of selection like below, square option won't appear:

<p>Li[st</p>
<ul>
    <li>One</li>
    <li>T]wo</li>
    <li>Three</li>
</ul>
<p>New paragraph.</p>

In case of selection like below, square option will appear but pressing it won't apply it to the element:

<p>List</p>
<ul>
    <li>One</li>
    <li>T[wo</li>
    <li>Three</li>
</ul>
<p>New ]paragraph.</p>

Squares also won't be applied in case of such situation:

<ul>
	<li>O[ne</li>
</ul>
<ul>
	<li>Tw]o</li>
</ul>

Fixing those cases would require much more work on it.

This bug was reported twice against Drupal 8.4, which was released a week ago.

See https://www.drupal.org/node/2911749.

We'd appreciate it if this could be fixed in a 4.7.x release, rather than having to wait for a 4.8.x release.

Please get this fix out as soon as humanly possible - I'd say it's a critical bug, and it's causing problems for many of my users.

@wimleers sorry that you guys had to wait for it till, 4.8.0 - unfortunately we were unable to get it in earlier.

@jonnott it's already merged to the major branch and waiting to be released. You can preview it in our nightly demos. 4.8.0 is scheduled at Dec 5th.
