#19993 Clipping in custom series off by 1 pixel

Fixed issues

Details

Before: What was the problem?

There is a boundary overflow issue when creating a clipping path in the custom series.

After: How does it behave after the fixing?

Modified part of the logic for the clipping path. Since the custom type does not include the lineStyle property, the thickness of the axis line cannot be correctly obtained. It is necessary to obtain the thickness of the axis lines before adjusting the position and size of the clipping path.
Changing the thickness of the axis lines will not cause overflow.
