All Open Documents BUT NOT every doc linked to them

I'm using Dreamweaver CC 18.0

Trying to do a simple Find & Replace like I've done for many, many years using "in Open Documents." For some reason, Dreamweaver wants to go into every single CSS and Javascript file referenced in the open HTML files. I don't care why somebody thought this was a good way for it to work from now on -- I just want to know how to stop it.

There is a little Show All File Types menu in the upper right and I can choose to not show either JS or CSS but I can't choose not to show both. I don't know if that's related ... it doesn't matter if I can't deselect both, I suppose.
