Many "Web Content" processes using memory?

Apologies if this has been brought up before, but I couldn’t find any topic on the matter.

I’ve just recently noticed lots of “Cubase 10 Web Content” processes using up a fair amount of memory. The weird thing is, the processes do not appear immediately after launching a project (but after an hour or two). I did not yet figure out what triggers them to show up.

Anyone knows why and how to get rid of them?

Got Cubase 10 Artist and Elements on Macbook Pro retina 2014 (Sierra). Same happens with both.
