Incorrect mdePopoverOffsetX and mdePopoverArrowOffsetX calculation on inverted state

[viktor-naboka-gl]

Bug:

In case if mdePopoverOffsetX was set popover positioning incorrect in the inverted state.

What is the expected behaviour?

In the inverted state (if space from expected side is not enough for view) offset must be calculated from inverted side.

What is the current behaviour?

Popover positioning in some case goes beyond the screen.
Offset works correct only for case when space on screen is enough for defined view position.

What are the steps to reproduce?

Similar issue also with mdePopoverArrowOffset.
Possible that Y offset also work incorrect please check it also.

Sorry I missed this issue.

I can confirm that does look like an issue with not calculating the arrow position dynamically. I will fix this when I have time unless someone else wants to add the dynamic arrow position feature.
