### Steps to Reproduce

1. Create a chart of any kind. (Tested: line and polar)
2. Add a tooltip.textStyle.lineHeight property. (Tested: 0.5 - 2)

### Current Behavior

Notice the tooltip layout default padding has been reset. (Updated the image)

### Expected Behavior

Default padding should not have any impact on lineHeight set or change.
