This part of the content is broken because the content in the tooltip gets from Gutenberg editor with extra symbols.
Check if the option “Clean tooltip text?” is enabled (Settings -> Tooltip tab). If yes or if it doesn’t help, we can advise using excerpt for tooltip instead of the content (Settings -> Tooltip tab -> Use term excerpt for hover?).
Sorry, I wasn’t clear. The tooltip is working fine, it is the glossary archive that is not looking good. Something is broken because I am seeing <p> </p> html instead of it being expressed. The project in progress is not public yet but you can see a screengrab of the problem here: https://timbaggaley.co.uk/tooltip-glossary-problem/
I’ve just installed on another site and same problem: https://timbaggaley.co.uk/glossary-2/
This bug related to the tooltip. If you hover over any term on the Glossary index page, it shows nothing because tooltip text was moved inside the link instead of data-cmtooltip argument.
If you look at this screenshot (https://www.screencast.com/t/bSB6C33l7nzq) you can see that in data-cmtooltip argument is only “<!– wp:paragraph –” and the rest of the tooltip data inside the .
This part was generated by Gutenberg editor and it can break the tooltip’s parser
We have an option to avoid such kind of bugs but it’s available only in the paid versions.
So we can only advise you to use excerpt instead of content (Settings -> Tooltip tab -> Use term excerpt for hover? option).
