Align options require extra click when used with Custom tags.

Steps

1. Create new e.g. Article.
2. Fill mandatory fields.
3. Insert one of the Custom tags e.g. youtube.
4. Enter valid url.
5. Save and Publish.
6. Return to edit mode.
7. Click the Custom tag.
8. Change the align option e.g. from Left to Right.
9. Publish immediately (without clicking anywhere else).

Actual: Align setting is not applied
Expected: Align setting is applied (the same way it works with Embed or Image)

Remarks: When before publishing user clicks on the richtext field again then setting is applied.
