cypress-real-events Add support for mouse scroll

Add support for mouse scroll as I couldn't get the cy.trigger("wheel") to work.

Thank you for this addition. Left a couple of comments

I see the 1 failling test, any ideas what can be the reason?

The build says the failure is in "realTouch".

This is what I found out. When test runs and scale is not 100% then test fails in certain cases. When the scale is 100% the all tests pass. So I've updated tests to set viewport small enough to get 100% scale.

What do you mean by scale? When window is zoomed? We have a guard for that and correctly handling this in getCypressElementCoorsinate

This one fails because the scale is not 100%. In the screenshot it says 86%.

This when it's 100% scale it passes. Strange..

I feel like there is something wrong with the way "position" is calculated when scale is not "1". When I do a "cy.trigger" the correct box receives the wheel event. cy.get(".main").trigger("wheel", { x: ($main.width() - $smallbox.width()) - 2, y, deltaX: 14, deltaY: 14 });

But when I do the same position for realMouseWheel it fails when scale is less than 1. cy.get(".main").realMouseWheel({ position: { x: ($main.width() - $smallbox.width()) - 2, y }, deltaX: 11, deltaY: 11 });

I'm calling "getCypressElementCoordinates". const { x, y } = getCypressElementCoordinates(subject, options.position, options.scrollBehavior);

Do you think there is a way to do it the way cypress does for "trigger" ?
