Hover bookmark - behavior

I use Opera as tool to develop and test/debug my web system (SaaS).
Opera only runs when I start my application at Visual Studio.
Opera has no plugin or any other changes.
The only personalization is that I keep at bookmark several localhost URLs from this system I've mentioned.

Since recently I've noticed some unexpected calls being made at Visual Studio backend.
This was noticed because I have several breakpoints, and unexpected breakpoints were being called upon.

Today I've noticed that whenever I hover a bookmark, this behavior happens.
I've searched for this but couldn't find anything related, therefore I don't know if this is due to Chromium or Opera itself.
Please note that there is nothing visually being rendered.

Is there a way to stop this behavior?
This is utterly bad for my daily routine to create/test/debug my web system.

I'm running latest Opera version: 107.0.5045.36
