Extension: Background worker huge memory footprint

When Opera gets sluggish, I open Developer > Task Manager and try sorting by Memory Footprint or CPU.
I usually see Extension: Background worker using lots of RAM. E.g. at the moment it's on 6GB!
I only have 3 extensions enabled (LastPass, Opera Ad Blocker, and a json formatter). Disabling all 3 extensions doesn't kill that process/task.
What is it, and why is it eating all my RAM?
I can 'End Process' in Opera's Task Manager and (apart from RAM usage / performance improving), nothing bad seems to happen. So I guess my question is how do I turn this useless thing off?

Maybe Gmail is a possible cause (or at least trigger)?
I will often put my Mac to sleep with Opera left open, and Gmail one of the handful of tabs kept open from that browsing session.
For example, this morning I see Opera using 2.4GB RAM, of which 1.4GB is the Extension: Background worker, and 540MB for the Gmail tab.
Because I use Gmail daily, it's hard for me to test the behaviour without it, but I will try to experiment with keeping it open vs. closing it and measuring what impact that has on Extension: Background worker memory growth.
