Looks like it’s a bug.
The reason you can’t add attributes in the Widget editor is because when the plugin is checking for wp.data.select('core/editor').canUserUseUnfilteredHTML() it returns false even though your user probably can use unfiltered HTML.
Since this restriction is only client-side, as a workaround you can paste this code into the JavaScript console (F12 -> Console) and then you should be able to add attributes (may need to unselect and reselect the block so that it re-renders first):
wp.data.select('core/editor').canUserUseUnfilteredHTML = () => true
The workaround will stop working after you reload the page, but if your user does in fact have unfiltered_html capability then the attributes will persist and you can use the workaround again to edit them later.
Thank you for the quick response.
The proposed solution makes the plugin usable in the widget area however it makes the work slightly longer. I was wondering: what do you mean by “bug” and “client-side restriction”? Basically what I would like to understand is if the proposed solution will always be needed, even in the future, or if there is hope for a permanent fix.
Thank you very much for your support. Regards,

The block editor team are in the process of unifying all the editors, so I would assume that it will start working eventually. Currently the editor is using the setting __experimentalCanUserUseUnfilteredHTML for determining this permission, so I will leave it for now, but once it is no longer experimental and still doesn’t work I’ll see if anything can be done on the plugin side.
Thank you, it is clear to me.
However, despite the workaround and the ability to put attributes in the widget blocks, they do not appear in the html code.
I tested the plugin with the page blocks and the attributes are inserted in the code, but this does not happen in the sidebar.
Obviously after each modification I clear each cache. But there still seems to be a problem on the widget blocks.
I will keep testing….

Resolved (Attributes are present in the html code. Probably a caching problem).
