Broken endnote tagging
When you use real endnotes in InDesign and export as a tagged PDF, the resulting tag tree is not generated properly.
This behavior can be reproduced for at least for InDesign 16, 17, 18.
Minium correct result:
In addition: The placement attribute for <Note> should be "Block".
This can only be fixed with a lot of work in the PDF.
@Chad und Adobe: As <Note> can contain a lot of different content, the content inside a note must be tagged appropriate – this can be as <P>, but <L>, <Figure>, even <Table> can be the right choice, too. This is critical and not optional (see ISO 32000 & 14289).
Yes e.g. PAC ist making a <P> inside a <Note> a warning, but we should never build PDFs for having good results in special software.

I agree however a <P> should not be allowed as a child of the <Note> tag AND while they're fixing this, please set the <Note> tags to be Block-level elements.
