The coordinate system inside CSS columns is different than inside a scrolling page (CSS positioning static/fixed/relative/absolute etc.)

Are your popups working with other reading systems? (e.g. MacOS Books.app / iOS iBooks)

[vigneshkumarelumalai]

No, we didn't check in other reading system

Please confirm aside footnote popup will work in readium app.

The Readium Chrome app / extension has not been updated for a while. However, Google updates the Chrome web browser regularly, so this may be the cause for a breaking change.

Note that 3 years ago, Google announced dropping support for Chrome apps: https://blog.chromium.org/2016/08/from-chrome-apps-to-web.html

Readium is still reachable directly via this link, but has not been referenced in the Chrome Web Store for some time: https://chrome.google.com/webstore/detail/readium/fepbnnnkkadjhjahcafoaglimekefifl

There is not active open-source development in readium-js-viewer (just occasional basic maintenance), which means that both the deprecated Chrome app and the online / cloud reader are now in "out of date" state (i.e. based on old library dependencies, and on an older technology stack).

There is active development in the Readium space, but both the architecture and the technology stack has been modernized, resulting in separate projects, and the deprecation of readium-js-viewer (and its "companion" projects readium-js, readium-shared-js, readium-cfi-js).
