[tmtron]

Version

5.3.2

Link to Minimal Reproduction

echarts online editor example

Steps to Reproduce

• the example shows a simple SVG map
• the SVG has 2 rectangles with the same name 'Item 1'
• when we assign a color to 'Item 1' it works as expected: both SVG elements have the red areaColor
• after 2 seconds a timer will dispatch the highlight action for 'Item 1'
• BUG: only one of the 2 SVG elements will be highlighted!

Current Behavior

only one of the 2 SVG elements named "Item 1" will be highlighted

Expected Behavior

all SVG elements named "Item 1" should be highlighted

Environment

- OS: Windows
- Browser: Chrome
- Framework: Angular
- but we can also reproduce it in the e-charts online editor (see reproduction example above)

This seems to be a bug. @tmtron Do you mind debugging to see what's wrong with it?
