Hi supportive people, you must get this one a lot. I'm aware of the filter options and have customised the Full-Html mode to not use the 3 offending filters, and cleared cache, but I'm still losing content.
I'm using the drupal 8(and 9) add a custom body block using layout designer, I then use the WYSIWYG editor in full-html mode with the filters (strip bad html/convert newline br+p/convert images -- see screenshot) disabled. However it is DELETING html from the end of the editor. I wonder if it's technically an empty paragraph as that has been mentioned in other issues (it isn't but has a link inside so doesn't have it's own text content).
Also, which module is actually doing the rich editing these days?
