Web Clipper opens new tab instead of showing dialog

[webclipperisgoodquestion 0]

System

• Safari: 14.0.3
• macos: 10.15.7
• Web Clipper: 7.13.6 - according to Safari Settings and App Store
• Web Clipper 1.0.11 (72) - according to Web Clipper/About (see attached image.png)

Steps To reproduce

1. Open a web page in Tab A
2. Open evernote in Tab B and login to evernote
3. go back to Tab A
4. click on the evernote elephant

Expected

• I see the dialog of the wonderful world of Oz, the web clipper

Actual observation

• A new tab with evernote is opened  - for my current plan (Trial Evernote Premium) I'm reminded that an evernote tab is already opened

Steps Taken

I tried all recommendations that I found in the forums:

• reducing cookie security setting (this should not be necessary for a 2021 application running natively on macos)
• re-activating
• restarting Safari and the whole universe
• uninstalling and reinstalling
  • Evernote App
  • Web Clipper

The issue is documented here since 2013, anyone has new intel on how this could be solved?
