Opera injecting unwanted code

Opera is injecting this piece of code while navigating:

<style type="text/css" id="operaUserStyle"></style>

I would like to know why, and how can I make it stop.

Started recently, probably around the version 94.0.4606.65, but it's still happening in the current version 94.0.4606.76.

Steps to reproduce: you can browse any webpage and Inspect it using Developer Tools... this piece of code will be there. Examples:

@edsongomes Couldn't find it here in Opera Developer 96.

@leocg Probably is a "bug" already solved in versions beyond the stable one. It's good to know, but would be nice to know if there is some way to solve the problem in the current stable version because this injection of code, even being harmless, is causing Opera to not function at all in some web systems who perform an integrity check in the html code before being able to operate.

@edsongomes I`ve checked again and could find it both in Stable and in Developer versions, but I needed to search for it, not something that will pop-up at your face.

And if you expand it, you will see that it's just the Lucid Mode script.

@leocg It's something that will pop-up at your face if you are using a web app which does an integrity check before clear the user access.

And it's happening even with Lucid Mode deactivated (but in this case, it's putting a blank <style> tag and nothing else, but enough to be blocked by an integrity check).

@edsongomes Well, I guess that 99% of the users don't keep checking integrity of the sites they visit.

It's not uncommon for browsers to add code to pages. They do it to fix problematic pages, to block ads, etc.

@leocg Yes, it's Very uncommon for a browser without any add-on, wallet or specific additional resource activated to add code to a page.

So, I appreciate your input, but I think you should let someone who knows the answer to the problem to help me, thank you.

@edsongomes At least here, it's the Lucid Mode script.

@edsongomes browser.js does add code to pages. It's used mainly to fix problematic pages
