Title: Flyout resize fix (4th)

When flyouts are dynamically resized, they wont hide properly as they
hide as if they were not resized.
This adds a listener to OnRenderSizeChanged which fixes
the issue.

Also added the fix from issue #260

Fixed pull request #284

Fixed for both left and right positioned flyouts.

This should hopefully be the final PR.
