Boost mode with categories causes points inside plot to disappear

[alrahemtulla]

Expected behaviour

Points inside the plot area should always be rendered

Actual behaviour

While scrolling after zoom, the points get clipped before they reach the edge of the plot.

Live demo with steps to reproduce

The series needs to be boosted and xAxis.categories must be set.

Zoom in and start scrolling horizontally. Notice that some points disappear early than we expect, and eventually most disappear before the category is off the screen.

Also notice that the points that DO appear near the edge of the plot, will not have tooltips.

Hello @alrahemtulla and thanks for reporting the issue.

Internal note: This bug is not related to Stock, it occurs in Core while zooming (demo) or just setting the axis extremes.
