Missing tooltips for annotations (with annotation contents)

See the 'package documentation' PDF file on this CTAN website: https://www.ctan.org/pkg/pdfcomment
There is a nice \pdftooltip feature. Upon hovering mouse cursor over pdftooltip'ed objects, a tooltip with user-defined text should appear. The 'package documentation' PDF file itself is an example.
This feature works perfectly with Microsoft Edge (Windows), SumatraPDF (Windows, Wine on Linux and macOS), Adobe Acrobat Reader (Windows and macOS), and Foxit reader (Windows, Linux, and macOS). It would be nice to have this feature on Evince as well!
