There are issues already written for adding clear to certain things, but it’s the same problem it’s always been in every editor: by default, it’s not cleared until the user clears it. The real issue is that there is not a good way for the user to put the clear in.
If you can define a CSS class in the Customizer like this:
.clear {clear: both;}
then you can put that class on whatever block you want to not wrap around the first one. (Or use an inline style style="clear:both;" on it)
The trick is to get it in there…

I’m self-hosted and fairly new to Gutenberg and wanted to inquire if this is something developers have included or are continuing to work on it.

Thank you
