"Go to Declaration" Shortcut is being fired by Ctrl+LMB

As of recently, the shortcut Ctrl+LBM, which was used a lot for quickly selecting entire strings/variables at once, started to behave like the “Go to Declaration” action, (which moves your script cursor and focus to the original variable declaration) which is bound to Ctrl+F12 by default, with no way of unbinding it whatsoever.

Is this a bug? intended? i can’t find anything about it anywhere, and if it’s indeed an intended change, without the possibility to disable it, it’s a bad one.
