Description

### 问题描述

在g2plot中,柱状图hover的默认行为是不管hover到元素内还是元素外,该列数据的背景色都会被显示出来;
在g2中,柱状图只在hover中元素时显示该列背景色,在元素之外则不会显示;
若要实现该效果,该如何进行配置呢?

Research direction

No source file, test, or reproduction link is identified. Start by comparing G2's bar-chart hover interaction with the stated G2Plot behavior and trace the existing interaction configuration; done means determining whether the background can be highlighted outside the bar and documenting a verified configuration or limitation.
