Is construction scripts running from content browser normal?

In several projects I have created, I noticed that after pressing play in editor at least once, when I move the mouse over the content browser window, it is executing the construction scripts of the blueprints shown in that window. Is this a normal behavior?

I found this after I added a print string to a construction script for debugging purposes. When my mouse is over the content browser, that print string is displaying. As a test, I added a print string to the construction script of several other blueprints that had no other code and it does the same thing. I am wondering if I have turned on or off some setting that is causing this or if it is just normal behavior?

There is an option that runs the construction script any time an object is edited versus at the end of the edit (meaning when you move an object its construction script is run as you are moving it vs solely after you let go of the mouse), but I’ve never seen the script running simply by mousing over the content browser.

To clarify, this is occurring outside of a PIE session, yes? When the editor isn’t running the game.

Thank you Shohei for your response. Yes, this is happening outside of PIE session, when my mouse is over the content browser the construction scripts start executing. I attached a screenshot of a simple project where I test some AI interaction. It seems very odd to me and I was hoping someone else had run into this and had an answer as to why.

Also happening for me. I’m unable to find the option that sets when the construction script is run.
