1) RichText Editor is not styled properly when changing block styles.

1. Embed content.
2. Type something.
3. Change style (e.g Heading 1)

View before change:

After:

2) Embed content item is not visible in edit mode.

1. Embed content.
2. Publish.
3. Edit.

3) Remove issue

1. Type some text.
2. Embed content item.
3. Remove content item.

Clicking Trash button on embed removes all content from block, not only embed content item. After removing embed toolbar still appears, RTE is blocked. User must click outside RTE or on Trash button again to see editor toolbar.

In console:

4) Toolbar in list block works only on list item, not whole block.

1. Add list block.
2. Add at least two list items.
3. Click on Move Up/Move Down/ Trash Button

Action works only on list item.

5) Toolbar in list block is not fixed.

@katarzynazawada 1, 2, 3, 4, 5 - fixed (please update also branch in richtext bundle)
6 as discussed in private have to be done in a separate ticket (we have the same issue for the custom tags in tables)
