Steps to Reproduce

$.getJSON(
ROOT_PATH + '/data-gl/asset/data/internet.graph.json',
function (graph) {
graph.edges.length = 10;
graph.nodes.length = 40;
var edges = graph.edges.map(function (edge) {
return {
source: edge[0],
target: edge[1],
value: 2
};
});
var categories = [];
var categoriesMap = {};
var nodes = graph.nodes.map(function (node) {
if (!categoriesMap[node[3]]) {
categories.push({
name: node[3]
});
categoriesMap[node[3]] = true;
}
return {
x: Math.random() * window.innerWidth,
y: Math.random() * window.innerHeight,
// x: node[0],
// y: node[1],
symbolSize: node[2],
category: node[3],
value: 1
};
});

Current Behavior

After the graphGL graphics set the title for the title, use the download picture function, only the title has no graphics after downloading, and other GL graphics should also have this problem

Expected Behavior

After setting the title and location, you can download the image display content.

I tried zlevel layering to achieve the effect of downloading and displaying content, but I don't quite understand that the zlevel of the title needs to be set higher than the zlevel of the graphics to work properly. According to the general rule, the zlevel of the graphics should be higher At the zlevel of the title?

The problem is with echarts-gl. Created a bug report there.
