Steps to reproduce:

• Configure a block custom style (inline: false) and activate it in your admin siteaccess
• Create or edit a content with a rich text field
• In the rich text field, insert a new custom style element
• Add and anchor ID on the custom style element
• Set the alignment of the custom style element
• Click on "Save"

Expected behaviour: the custom style element has the anchor and the alignment that has been previously set

Actual behaviour: the anchor and alignment is not present after saving

Additional information: it seems that these attributes are not saved at all in the database. The only info that is saved is the "ez-has-anchor" class, which is added when adding an anchor. The information stored in database looks like this :

<eztemplate ezxhtml:class="ez-has-anchor" name="my_custom_style" type="style">
    <ezcontent>test</ezcontent>
</eztemplate>
