Touch context menu on Google websites

A Former User

I've been trying to find answers without posting but the issue that I'm having seems no to have been described yet.

Some basic data about systems I tested:
Windows 7 x32
Windows 10 x64
Opera 66.0.3515.44

Problem is concerning only navigating by using touch screen.

And here is the issue:
When I open a google website such as Youtube or Gmail the context menu is not showing up (in certain areas of that page) while doing the long press (single touch) - this "gesture" is recognized by Windows as a "right click" and normally brings up a context menu. Like this:

And the key problem for me is that at the moment I have no way to open this context menu by touch - I use this mostly to open YT videos in a separate tab.

In the earlier version of Opera, if I was lucky and touched a very narrow frame around the video thumbnail, then the context menu would show up.

Now whatever I do, Opera is just registering a "short touch" and opens the video in the same tab.

I checked 2 laptops and 3 Windows installations - all give the same result.

Does anyone else have this problem?

Any workarounds?

Thanks,
Mike
