Safari developer tools keep to open console in a row of elements tab

Hello,

since the update to macOS enter 13.3 (yesterday evening) I'm experiencing a new behavior in Safari developer tools. I guess it's an unexpected behavior and I can't find the way to stop it.

When I open developer tools (default elements tab) and I start to inspect an element in the page, a new row appears automatically in the elements tab; this row is related to the console (which is normally in the other tab).

If I close that row by the proper button, each time I inspect something else on the page, it appears again. Someone has idea how to disable this feature? I tried looking here and on Google, but I wasn't lucky.

I attach a screenshot to show which button I'm clicking to close it.

Any help is appreciated.
