Marker display is abnormal

[Ella-Sun]

In the bar chart, if you click on the last few columns, the bubble will appear in a position offset where it should be.
If I change BalloonMarker.swift in the 63rd line of code x: point.x + offset.x, as x: point.x,, it shows normal.

Confirmed in lien chart as well.

It's actually not a bug, but a feature, as they say...
Instead of the marker being cut by the view, it is offset to stay in the view. This behavior can be enabled/disabled/customized by any custom marker.
This specific marker is simplistic, and the arrow does not move to reflect the correct position within the marker, as I did not have much time to invest in the demos...
